Annex A
Section 1. Form of Notes.
(a) The Notes shall be sold initially only (A) to persons reasonably believed to be Qualified Institutional Buyers as defined in Rule 144A (“QIBs”) in reliance on Rule 144A or (B) outside the United States, to persons other than “U.S. persons” as defined in Rule 902 under the Securities Act in compliance with Regulation S. Notes may thereafter be transferred to, among others, purchasers reasonably believed to be QIBs, purchasers in reliance on Regulation S, and otherwise, subject to the restrictions on transfer set forth herein. Notes initially resold pursuant to Rule 144A shall be initially issued in the form of one or more permanent global securities in fully registered form (collectively, the “Rule 144A Global Note”) and Notes initially resold pursuant to Regulation S shall be initially issued in the form of one or more permanent global securities in fully registered form (collectively, the “Regulation S Global Note” and, together with the Rule 144A Global Note, the “Global Notes” and, each, a “Global Note”), in each case without interest coupons and with the applicable Private Placement Legends set forth in Section 2 hereof. A Rule 144A Global Note and all other Notes, if any, evidencing the debt, or any portion of the debt, initially evidenced by such Rule 144A Global Notes, shall collectively be referred to herein as the “Rule 144A Notes,” and a Regulation S Global Note and all other Notes, if any, evidencing the debt, or any portion of the debt, initially evidenced by such Rule 144A Global Notes, shall collectively be referred to herein as the “Regulation S Notes.”
(b) The Global Notes shall be deposited with The Depository Trust Company (“DTC”) as the depositary for such Notes (the “Depository”). The Notes shall be issued as fully registered securities in the name of Cede & Co., DTC’s nominee, and shall be deposited with, or on behalf of, DTC. Subject to the provisions set forth herein, a Global Note shall be exchangeable for definitive Notes in registered form, bearing interest at the same rate, having the same date of issuance, Stated Maturity and other terms and of differing denominations aggregating a like amount, only if (i) the Depository (a) notifies the Company that it is unwilling or unable to continue as Depository or clearing system for such Global Note or (b) ceases to be a “clearing agency” registered under the Securities Exchange Act of 1934, as amended, and in either event the Company is unable to find a qualified replacement for the Depository within 90 days, (ii) the Company in its sole discretion determines that all such Global Notes shall be exchangeable for definitive Notes in registered form or (iii) there has occurred and is continuing an Event of Default with respect to the Notes and the Depository notifies the Trustee of its decision to exchange such Global Notes for definitive Notes in registered form. Such definitive Notes shall be registered in the names of the owners of the beneficial interests in such Global Note as provided by the Depository’s relevant participants (as such participants are identified by the Depository holding such Global Note). Subject to the provisions set forth herein, each Global Note shall not be exchangeable, except for a Global Note of like denomination to be registered in the name of the Depository or its nominee.

Section 2. Special Transfer Provisions.
(a) If a Holder of a beneficial interest in a Rule 144A Global Note wishes at any time to exchange its interest in such Rule 144A Global Note for an interest in a Regulation S Global Note, or to transfer its interest in such Rule 144A Global Note to a Person who wishes to take delivery thereof in the form of an interest in a Regulation S Global Note, such Holder may, subject to the rules and procedures of DTC to the extent applicable, and to the requirements set forth in the following sentence, exchange or cause the exchange or transfer or cause the transfer of such interest for an equivalent beneficial interest in such Regulation S Global Note. Upon receipt by the Security Registrar at its offices of (1) written instructions given in accordance with the procedures of DTC, to the extent applicable, from or on behalf of a Holder of a beneficial interest in a Rule 144A Global Note, to credit or cause to be credited a beneficial interest in a Regulation S Global Note in an amount equal to the beneficial interest in the Rule 144A Global Note to be exchanged or transferred, (2) a written order given in accordance with the procedures of DTC, to the extent applicable, containing information regarding the account to be credited with such increase and the name of such account, and (3) a certificate given by the Holder of such beneficial interest stating that the exchange or transfer of such interest has been made pursuant to and in accordance with Rule 904 of Regulation S, the Security Registrar shall promptly reduce or reflect on its records a reduction of such Rule 144A Global Note by the aggregate principal amount of the beneficial interest in such Rule 144A Global Note to be so exchanged or transferred from the relevant participant, and the Security Registrar shall promptly, concurrently with such reduction, increase or reflect on its records an increase of the principal amount of such Regulation S Global Note by the aggregate principal amount of the beneficial interest in such Rule 144A Global Note to be so exchanged or transferred, and to credit or cause to be credited to the account of the Person specified in such instructions a beneficial interest in such Regulation S Global Note in an amount equal to the reduction in the principal amount of such Rule 144A Global Note.
(b) If a Holder of a beneficial interest in a Regulation S Global Note wishes at any time to exchange its interest in such Regulation S Global Note for an interest in a Rule 144A Global Note, or to transfer its interest in such Regulation S Global Note to a Person who wishes to take delivery thereof in the form of an interest in a Rule 144A Global Note, such Holder may, subject to the rules and procedures of DTC, to the extent applicable, and to the requirements set forth in the following sentence, exchange or cause the exchange or transfer or cause the transfer of such interest for an equivalent beneficial interest in such Rule 144A Global Note. Upon receipt by the Security Registrar at its offices of (1) instructions given in accordance with the procedures of DTC, to the extent applicable, from or on behalf of a beneficial owner of an interest in a Regulation S Global Note, to credit or cause to be credited a beneficial interest in a Rule 144A Global Note in an amount equal to the beneficial interest in the Regulation S Global Note to be exchanged or transferred, (2) a written order given in accordance with the procedures of DTC, to the extent applicable, containing information regarding the account to be credited with such increase and the name of such account, and (3) prior to or on the 40th day after the later of the commencement of the offering of the Notes and the relevant issuance date of the Notes (the “Restricted Period”), a certificate given by the Holder of such beneficial interest and stating that the Person transferring such interest in such Regulation S Global Note reasonably believes that the Person acquiring such interest in such Rule 144A Global Note is a QIB and is obtaining such beneficial interest in a transaction meeting the requirements of Rule 144A and any applicable securities laws of any state of the United States or any other jurisdiction, the Security Registrar shall promptly reduce or reflect on its records a reduction of such Regulation S Global Note by the aggregate principal amount of the beneficial interest in such Regulation S Global Note to be exchanged or transferred, and the Security Registrar shall promptly increase or reflect on its records an increase of the principal amount of such Rule 144A Note by the aggregate principal amount of the beneficial interest in such Regulation S Global Note to be so exchanged or transferred, and to credit or cause to be credited to the account of the Person specified in such instructions a beneficial interest in such Rule 144A Global Note equal to the reduction in the principal amount of such Regulation S Global Note. After the expiration of the Restricted Period, the certification requirement set forth in clause (3) of the second sentence of this Section 2(b) will no longer apply to such transfers.

(c) Any beneficial interest in one of the Global Notes that is transferred to a Person who takes delivery in the form of an interest in another Global Note will, upon transfer, cease to be an interest in such Global Note and become an interest in the other Global Note and, accordingly, will thereafter be subject to all transfer restrictions and other procedures applicable to beneficial interests in such other Global Note for as long as it remains such an interest.
(d) In the event that a Global Note is exchanged for definitive Notes in registered form without interest coupons or a definitive Note in registered form without interest coupons is exchanged for another such definitive Note in registered form without interest coupons, or a definitive Note is exchanged for a beneficial interest in a Global Note, such Notes may be exchanged or transferred for one another only in accordance with such procedures as are substantially consistent with the provisions of Sections 2(a), 2(b) and 2(c) above (including the certification requirements intended to ensure that such exchanges or transfers comply with Rule 144, Rule 144A or Regulation S, as the case may be) and as may be from time to time adopted by the Company and the Trustee.
(e) Prior to the expiration of the Restricted Period relating to any Regulation S Global Notes, beneficial interests in the relevant Regulation S Global Notes may only be exchanged or transferred in accordance with the certification requirements hereof.
(f) Each Rule 144A Note and Regulation S Note issued hereunder shall, upon issuance, bear the applicable Private Placement Legends (as defined herein), and such legends shall not be removed from such Note except as provided herein. The Rule 144A Legend may be removed from a Rule 144A Note if there is delivered to the Company and the Trustee such satisfactory evidence, which may include an opinion of independent counsel licensed to practice law in the State of New York as may be reasonably required by the Company and the Trustee, that neither such legend nor the restrictions on transfer set forth therein are required to ensure that transfers of such Note will not violate the registration requirements of the Securities Act. Upon provision of such satisfactory evidence, the Trustee, at the written direction of the Company, shall authenticate and deliver in exchange for such Note another Note or Notes having an equal aggregate principal amount that does not bear such legend. If the Rule 144A Legend has been removed from a Rule 144A Note as provided above, no other Note issued in exchange for all or part of such Note shall bear such legend, unless the Company has reasonable cause to believe that such other Note is a “Restricted Security” within the meaning of Rule 144 and instructs the Trustee to cause a legend to appear thereon. In addition, upon the consummation of the Exchange Offer (as defined in the Registration Rights Agreement, dated as of the date hereof, by and among the Company and BofA Securities, Inc., Citigroup Global Markets Inc., Morgan Stanley & Co., Deutsche Bank Securities Inc., Goldman Sachs & Co. LLC and J.P. Morgan Securities LLC (the “Registration Rights Agreement”)), such Private Placement Legends shall be removed from such Notes which are exchanged. All requirements pertaining to Rule 144A Global Notes and Regulation S Notes will still apply with respect to Holders of such Notes that do not exchange such Notes pursuant to the Exchange Offer, and Exchange Notes (as defined in the Registration Rights Agreement) in certificated or global form, in each case without the Private Placement Legends will be available to Holders that exchange such Notes in such Exchange Offer.

[REVERSE OF SECURITY]

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Amended and Restated Indenture, dated as of May 1, 2001, as it may be supplemented from time to time (herein called the “Indenture”), between the Company (formerly known as United Technologies Corporation) and The Bank of New York Mellon Trust Company, N.A. (formerly The Bank of New York Trust Company, N.A.), as Trustee (successor to The Bank of New York) (herein called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the series of which this Security is a part), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof. The Indenture does not limit the aggregate principal amount of the Securities or the Securities of this series that may be issued thereunder. Additional Securities of this series may be issued from time to time hereafter; provided that any such additional Securities that are not fungible with this Security for U.S. federal income tax purposes will have a separate CUSIP, ISIN and other identifying number than this Security.

The Company may not redeem all or any part of this Security prior to its maturity.

This Security is not repayable at the option of the Holder hereof and is not subject to the operation of any sinking fund.

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

The provisions of Section 1402 and Section 1403 of the Indenture relating to defeasance and covenant defeasance, respectively, shall apply to this Security. Pursuant to Section 1404(5) and Section 1404(6) of the Indenture, any such defeasance or covenant defeasance shall be conditioned on receipt of an Opinion of Counsel relating to the federal income tax consequences of such defeasance or covenant defeasance.

The Company will not pay any Additional Amounts to Holders that are not U.S. persons (including any modification to the definition of such term) in respect of any tax, assessment or governmental charge.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of all Securities at the time Outstanding to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Outstanding Securities, to waive compliance by the Company with certain provisions of the Indenture, and contains provisions permitting the Holders of specified percentages in principal amount, in certain

instances of the Outstanding Securities of individual series and in other instances of all Securities at the time Outstanding, to waive on behalf of all of the Holders of Securities of such individual series or of the Holders of all Securities at the time Outstanding, as the case may be, certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount, in certain instances of the Securities of this series at the time Outstanding and in other instances of all Outstanding Securities, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of not less than a majority in principal amount of Securities of this series at the time Outstanding or of all Outstanding Securities, as the case may be, a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof (and premium, if any) or interest hereon on or after the respective due dates expressed herein.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or make provision as provided in Article Fourteen of the Indenture for the payment of the amount of principal of (and premium, if any) and interest on this Security herein provided, and at the times, place and rate, and in the coin or currency, herein prescribed.

The Securities of this series are issuable only in registered form without coupons in minimum denominations of $2,000 and any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series of a different authorized denomination, as requested by the Holder surrendering the same.

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Amended and Restated Indenture, dated as of May 1, 2001, as it may be supplemented from time to time (herein called the “Indenture”), between the Company (formerly known as United Technologies Corporation) and The Bank of New York Mellon Trust Company, N.A. (formerly The Bank of New York Trust Company, N.A.), as Trustee (successor to The Bank of New York) (herein called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the series of which this Security is a part), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof. The Indenture does not limit the aggregate principal amount of the Securities or the Securities of this series that may be issued thereunder. Additional Securities of this series may be issued from time to time hereafter; provided that any such additional Securities that are not fungible with this Security for U.S. federal income tax purposes will have a separate CUSIP, ISIN and other identifying number than this Security.

The Company may not redeem all or any part of this Security prior to its maturity.

This Security is not repayable at the option of the Holder hereof and is not subject to the operation of any sinking fund.

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

The provisions of Section 1402 and Section 1403 of the Indenture relating to defeasance and covenant defeasance, respectively, shall apply to this Security. Pursuant to Section 1404(5) and Section 1404(6) of the Indenture, any such defeasance or covenant defeasance shall be conditioned on receipt of an Opinion of Counsel relating to the federal income tax consequences of such defeasance or covenant defeasance.

The Company will not pay any Additional Amounts to Holders that are not U.S. persons (including any modification to the definition of such term) in respect of any tax, assessment or governmental charge.

instances of the Outstanding Securities of individual series and in other instances of all Securities at the time Outstanding, to waive on behalf of all of the Holders of Securities of such individual series or of the Holders of all Securities at the time Outstanding, as the case may be, certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount, in certain instances of the Securities of this series at the time Outstanding and in other instances of all Outstanding Securities, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of not less than a majority in principal amount of Securities of this series at the time Outstanding or of all Outstanding Securities, as the case may be, a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof (and premium, if any) or interest hereon on or after the respective due dates expressed herein.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or make provision as provided in Article Fourteen of the Indenture for the payment of the amount of principal of (and premium, if any) and interest on this Security herein provided, and at the times, place and rate, and in the coin or currency, herein prescribed.

As provided in the Indenture and subject to certain limitations therein and herein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

The Securities of this series are issuable only in registered form without coupons in minimum denominations of $2,000 and any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series of a different authorized denomination, as requested by the Holder surrendering the same.

[REVERSE OF SECURITY]

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Amended and Restated Indenture, dated as of May 1, 2001, as it may be supplemented from time to time (herein called the “Indenture”), between the Company (formerly known as United Technologies Corporation) and The Bank of New York Mellon Trust Company, N.A. (formerly The Bank of New York Trust Company, N.A.), as Trustee (successor to The Bank of New York) (herein called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the series of which this Security is a part), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof. The Indenture does not limit the aggregate principal amount of the Securities or the Securities of this series that may be issued thereunder. Additional Securities of this series may be issued from time to time hereafter; provided that any such additional Securities that are not fungible with this Security for U.S. federal income tax purposes will have a separate CUSIP, ISIN and other identifying number than this Security.

The Company may not redeem all or any part of this Security prior to its maturity.

This Security is not repayable at the option of the Holder hereof and is not subject to the operation of any sinking fund.

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

The provisions of Section 1402 and Section 1403 of the Indenture relating to defeasance and covenant defeasance, respectively, shall apply to this Security. Pursuant to Section 1404(5) and Section 1404(6) of the Indenture, any such defeasance or covenant defeasance shall be conditioned on receipt of an Opinion of Counsel relating to the federal income tax consequences of such defeasance or covenant defeasance.

The Company will not pay any Additional Amounts to Holders that are not U.S. persons (including any modification to the definition of such term) in respect of any tax, assessment or governmental charge.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of all Securities at the time Outstanding to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Outstanding Securities, to waive compliance by the Company with certain provisions of the Indenture, and contains provisions permitting the Holders of specified percentages in principal amount, in certain

instances of the Outstanding Securities of individual series and in other instances of all Securities at the time Outstanding, to waive on behalf of all of the Holders of Securities of such individual series or of the Holders of all Securities at the time Outstanding, as the case may be, certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount, in certain instances of the Securities of this series at the time Outstanding and in other instances of all Outstanding Securities, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of not less than a majority in principal amount of Securities of this series at the time Outstanding or of all Outstanding Securities, as the case may be, a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof (and premium, if any) or interest hereon on or after the respective due dates expressed herein.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or make provision as provided in Article Fourteen of the Indenture for the payment of the amount of principal of (and premium, if any) and interest on this Security herein provided, and at the times, place and rate, and in the coin or currency, herein prescribed.

The Securities of this series are issuable only in registered form without coupons in minimum denominations of $2,000 and any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series of a different authorized denomination, as requested by the Holder surrendering the same.

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

(formerly The Bank of New York Trust Company, N.A.), as Trustee (successor to The Bank of New York) (herein called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the series of which this Security is a part), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof. The Indenture does not limit the aggregate principal amount of the Securities or the Securities of this series that may be issued thereunder. Additional Securities of this series may be issued from time to time hereafter; provided that any such additional Securities that are not fungible with this Security for U.S. federal income tax purposes will have a separate CUSIP, ISIN and other identifying number than this Security.

The Company may not redeem all or any part of this Security prior to its maturity.

This Security is not repayable at the option of the Holder hereof and is not subject to the operation of any sinking fund.

The provisions of Section 1402 and Section 1403 of the Indenture relating to defeasance and covenant defeasance, respectively, shall apply to this Security. Pursuant to Section 1404(5) and Section 1404(6) of the Indenture, any such defeasance or covenant defeasance shall be conditioned on receipt of an Opinion of Counsel relating to the federal income tax consequences of such defeasance or covenant defeasance.

The Company will not pay any Additional Amounts to Holders that are not U.S. persons (including any modification to the definition of such term) in respect of any tax, assessment or governmental charge.

Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount, in certain instances of the Securities of this series at the time Outstanding and in other instances of all Outstanding Securities, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of not less than a majority in principal amount of Securities of this series at the time Outstanding or of all Outstanding Securities, as the case may be, a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof (and premium, if any) or interest hereon on or after the respective due dates expressed herein.

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Amended and Restated Indenture, dated as of May 1, 2001, as it may be supplemented from time to time (herein called the “Indenture”), between the Company (formerly known as United Technologies Corporation) and The Bank of New York Mellon Trust Company, N.A. (formerly The Bank of New York Trust Company, N.A.), as Trustee (successor to The Bank of New York) (herein called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the series of which this Security is a part), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof. The Indenture does not limit the aggregate principal amount of the Securities or the Securities of this series that may be issued thereunder. Additional Securities of this series may be issued from time to time hereafter; provided that any such additional Securities that are not fungible with this Security for U.S. federal income tax purposes will have a separate CUSIP, ISIN and other identifying number than this Security.

The Company may not redeem all or any part of this Security prior to its maturity. This Security is not repayable at the option of the Holder hereof and is not subject to the operation of any sinking fund.

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

The provisions of Section 1402 and Section 1403 of the Indenture relating to defeasance and covenant defeasance, respectively, shall apply to this Security. Pursuant to Section 1404(5) and Section 1404(6) of the Indenture, any such defeasance or covenant defeasance shall be conditioned on receipt of an Opinion of Counsel relating to the federal income tax consequences of such defeasance or covenant defeasance.

The Company will not pay any Additional Amounts to Holders that are not U.S. persons (including any modification to the definition of such term) in respect of any tax, assessment or governmental charge.

The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Outstanding Securities, to waive compliance by the Company with certain provisions of the Indenture, and contains provisions permitting the Holders of specified percentages in principal amount, in certain instances of the Outstanding Securities of individual series and in other instances of all Securities

at the time Outstanding, to waive on behalf of all of the Holders of Securities of such individual series or of the Holders of all Securities at the time Outstanding, as the case may be, certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount, in certain instances of the Securities of this series at the time Outstanding and in other instances of all Outstanding Securities, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of not less than a majority in principal amount of Securities of this series at the time Outstanding or of all Outstanding Securities, as the case may be, a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof (and premium, if any) or interest hereon on or after the respective due dates expressed herein.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or make provision as provided in Article Fourteen of the Indenture for the payment of the amount of principal of (and premium, if any) and interest on this Security herein provided, and at the times, place and rate, and in the coin or currency, herein prescribed.

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Amended and Restated Indenture, dated as of May 1, 2001, as it may be supplemented from time to time (herein called the “Indenture”), between the Company (formerly known as United Technologies Corporation) and The Bank of New York Mellon Trust Company, N.A. (formerly The Bank of New York Trust Company, N.A.), as Trustee (successor to The Bank of New York) (herein called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the series of which this Security is a part), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof. The Indenture does not limit the aggregate principal amount of the Securities or the Securities of this series that may be issued thereunder. Additional Securities of this series may be issued from time to time hereafter; provided that any such additional Securities that are not fungible with this Security for U.S. federal income tax purposes will have a separate CUSIP, ISIN and other identifying number than this Security.

The Company may not redeem all or any part of this Security prior to its maturity.

This Security is not repayable at the option of the Holder hereof and is not subject to the operation of any sinking fund.

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

The provisions of Section 1402 and Section 1403 of the Indenture relating to defeasance and covenant defeasance, respectively, shall apply to this Security. Pursuant to Section 1404(5) and Section 1404(6) of the Indenture, any such defeasance or covenant defeasance shall be conditioned on receipt of an Opinion of Counsel relating to the federal income tax consequences of such defeasance or covenant defeasance.

The Company will not pay any Additional Amounts to Holders that are not U.S. persons (including any modification to the definition of such term) in respect of any tax, assessment or governmental charge.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of all Securities at the time Outstanding to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Outstanding Securities, to waive compliance by the Company with certain provisions of the Indenture, and contains provisions permitting the Holders of specified percentages in principal amount, in certain

instances of the Outstanding Securities of individual series and in other instances of all Securities at the time Outstanding, to waive on behalf of all of the Holders of Securities of such individual series or of the Holders of all Securities at the time Outstanding, as the case may be, certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount, in certain instances of the Securities of this series at the time Outstanding and in other instances of all Outstanding Securities, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of not less than a majority in principal amount of Securities of this series at the time Outstanding or of all Outstanding Securities, as the case may be, a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof (and premium, if any) or interest hereon on or after the respective due dates expressed herein.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or make provision as provided in Article Fourteen of the Indenture for the payment of the amount of principal of (and premium, if any) and interest on this Security herein provided, and at the times, place and rate, and in the coin or currency, herein prescribed.

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Amended and Restated Indenture, dated as of May 1, 2001, as it may be supplemented from time to time (herein called the “Indenture”), between the Company (formerly known as United Technologies Corporation) and The Bank of New York Mellon Trust Company, N.A. (formerly The Bank of New York Trust Company, N.A.), as Trustee (successor to The Bank of New York) (herein called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the series of which this Security is a part), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof. The Indenture does not limit the aggregate principal amount of the Securities or the Securities of this series that may be issued thereunder. Additional Securities of this series may be issued from time to time hereafter; provided that any such additional Securities that are not fungible with this Security for U.S. federal income tax purposes will have a separate CUSIP, ISIN and other identifying number than this Security.

The Company may not redeem all or any part of this Security prior to its maturity.

This Security is not repayable at the option of the Holder hereof and is not subject to the operation of any sinking fund.

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

The provisions of Section 1402 and Section 1403 of the Indenture relating to defeasance and covenant defeasance, respectively, shall apply to this Security. Pursuant to Section 1404(5) and Section 1404(6) of the Indenture, any such defeasance or covenant defeasance shall be conditioned on receipt of an Opinion of Counsel relating to the federal income tax consequences of such defeasance or covenant defeasance.

The Company will not pay any Additional Amounts to Holders that are not U.S. persons (including any modification to the definition of such term) in respect of any tax, assessment or governmental charge.

The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Outstanding Securities, to waive compliance by the Company with certain provisions of the Indenture, and contains provisions permitting the Holders of specified percentages in principal amount, in certain

instances of the Outstanding Securities of individual series and in other instances of all Securities at the time Outstanding, to waive on behalf of all of the Holders of Securities of such individual series or of the Holders of all Securities at the time Outstanding, as the case may be, certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount, in certain instances of the Securities of this series at the time Outstanding and in other instances of all Outstanding Securities, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of not less than a majority in principal amount of Securities of this series at the time Outstanding or of all Outstanding Securities, as the case may be, a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof (and premium, if any) or interest hereon on or after the respective due dates expressed herein.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or make provision as provided in Article Fourteen of the Indenture for the payment of the amount of principal of (and premium, if any) and interest on this Security herein provided, and at the times, place and rate, and in the coin or currency, herein prescribed.

|  |  | By: |
|  |  |  |  | Authorized Signatory

[REVERSE OF SECURITY]
This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Amended and Restated Indenture, dated as of May 1, 2001, as it may be supplemented from time to time (herein called the “Indenture”), between the Company (formerly known as United Technologies Corporation) and The Bank of New York Mellon Trust Company, N.A. (formerly The Bank of New York Trust Company, N.A.), as Trustee (successor to The Bank of New York) (herein called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the series of which this Security is a part), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof. The Indenture does not limit the aggregate principal amount of the Securities or the Securities of this series that may be issued thereunder. Additional Securities of this series may be issued from time to time hereafter; provided that any such additional Securities that are not fungible with this Security for U.S. federal income tax purposes will have a separate CUSIP, ISIN and other identifying number than this Security.
The Company may, at its option, redeem all or any part of this Security. If it chooses to do so, it shall mail or electronically deliver according to the procedures of DTC a notice of redemption (the “Redemption Notice”) to the Holder hereof (with a copy to the Trustee) not less than 15 days and not more than 60 days before the Redemption Date. The Redemption Price shall equal the greater of (i) 100% of the principal amount of this Security to be redeemed or (ii) the sum of the present values of the Remaining Scheduled Payments on the principal amount of this Security to be redeemed, discounted to the Redemption Date on a semiannual basis, assuming a 360-day year consisting of twelve 30-day months, at the Treasury Rate plus 30 basis points. The Redemption Price shall also include interest accrued to, but excluding, the Redemption Date on the principal balance of this Security to be redeemed.
“Treasury Rate” means, for any Redemption Date, the annual rate equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue equal to the Comparable Treasury Price, expressed as a percentage of its principal amount, for that Redemption Date. The yield of the Comparable Treasury Issue will be computed as of the second Business Day immediately preceding the date of the Redemption Notice.
“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent (defined below) that has a maturity comparable to the remaining maturity of this Security and that would be used in accordance with customary financial practice to price new issues of corporate debt securities with a maturity comparable to the remaining term of the Securities. The investment banks from which the Company will select a Quotation Agent are BofA Securities, Inc., Citigroup Global Markets Inc. and Morgan Stanley & Co. LLC, or their respective successors, or up to two other nationally recognized investment banking firms that are primary U.S. government securities dealers in New York City (each, a “Reference Treasury Dealer”). The Company will select one of the Reference Treasury Dealers to serve as its quotation agent (the “Quotation Agent”). If any of the firms referenced in the second

preceding sentence ceases to be a primary dealer of U.S. government securities in New York City, the Company shall appoint another nationally recognized investment banking firm that is a primary dealer as a substitute.
“Comparable Treasury Price” means, for any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations given to the Trustee by the Reference Treasury Dealers for that Redemption Date after excluding the highest and lowest of those Reference Treasury Dealer Quotations (or only one of the highest or lowest of the Reference Treasury Dealer Quotations if there are more than one), or (2) if the Trustee is given fewer than four Reference Treasury Dealer Quotations, the average of all those quotations.
“Reference Treasury Dealer Quotation” means, with respect to any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the Trustee by a Reference Treasury Dealer as of 3:30 p.m., New York time, on the second Business Day preceding the date of the Redemption Notice. The Trustee shall seek Reference Treasury Dealer Quotations in respect of any Redemption Date from each of the then-existing Reference Treasury Dealers.
“Remaining Scheduled Payments” means, with respect to the principal amount of each Security being redeemed, the remaining scheduled payments of principal and interest on that Security that would be due after the related Redemption Date but for the redemption. If, however, the Redemption Date is not an Interest Payment Date with respect to that Security, the amount of the next succeeding scheduled interest payment on that Security that would have been due will be deemed reduced by the amount of interest accrued on the Security to the Redemption Date.
On and after any Redemption Date, interest shall cease to accrue with respect to the Securities, or any portion of the Securities, called for redemption and for which the Redemption Price has been paid or made available for payment. On or prior to any Redemption Date, the Company shall deposit with the Paying Agent or the Trustee money sufficient to pay the Redemption Price on the Securities to be redeemed on such Redemption Date. If less than all of the Securities of this series are redeemed, the Trustee shall choose the Securities of this series to be redeemed by any method that it deems fair and appropriate, provided that if the Securities of this series are represented by one or more global Securities, interests in the Securities of this series will be selected for redemption by DTC in accordance with its standard procedures therefor.
Notwithstanding Section 1104 of the Indenture, the notice of any redemption referred to herein need not set forth the Redemption Price therefor but only the manner of calculation thereof. Promptly after the calculation of such Redemption Price, the Company shall give the Trustee notice thereof and the Trustee shall not be responsible for such calculation.
This Security is not repayable at the option of the Holder hereof and is not subject to the operation of any sinking fund.

Pursuant to Section 1404(5) and Section 1404(6) of the Indenture, any such defeasance or covenant defeasance shall be conditioned on receipt of an Opinion of Counsel relating to the federal income tax consequences of such defeasance or covenant defeasance.
The Company will not pay any Additional Amounts to Holders that are not U.S. persons (including any modification to the definition of such term) in respect of any tax, assessment or governmental charge.
The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of all Securities at the time Outstanding to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Outstanding Securities, to waive compliance by the Company with certain provisions of the Indenture, and contains provisions permitting the Holders of specified percentages in principal amount, in certain instances of the Outstanding Securities of individual series and in other instances of all Securities at the time Outstanding, to waive on behalf of all of the Holders of Securities of such individual series or of the Holders of all Securities at the time Outstanding, as the case may be, certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.
As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount, in certain instances of the Securities of this series at the time Outstanding and in other instances of all Outstanding Securities, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of not less than a majority in principal amount of Securities of this series at the time Outstanding or of all Outstanding Securities, as the case may be, a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for

the enforcement of any payment of principal hereof (and premium, if any) or interest hereon on or after the respective due dates expressed herein.
No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or make provision as provided in Article Fourteen of the Indenture for the payment of the amount of principal of (and premium, if any) and interest on this Security herein provided, and at the times, place and rate, and in the coin or currency, herein prescribed.

registered assigns, the principal sum of ZERO DOLLARS ($0) on July 1, 2036, and to pay interest thereon (computed on the basis of a 360-day year comprised of twelve 30-day months) from January 1, 2020 or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semiannually in arrears on January 1 and July 1 of each year, and on the maturity date, commencing on July 1, 2020, at the rate of 6.800% per annum, until the principal hereof is paid or made available for payment.

TRUSTEE’S CERTIFICATE OF AUTHENTICATION
This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

|  |  | By: |
|  |  |  |  | Authorized Signatory
Dated: |  |  |  |  |

[REVERSE OF SECURITY]
This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Amended and Restated Indenture, dated as of May 1, 2001, as it may be supplemented from time to time (herein called the “Indenture”), between the Company (formerly known as United Technologies Corporation) and The Bank of New York Mellon Trust Company, N.A. (formerly The Bank of New York Trust Company, N.A.), as Trustee (successor to The Bank of New York) (herein called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the series of which this Security is a part), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof. The Indenture does not limit the aggregate principal amount of the Securities or the Securities of this series that may be issued thereunder. Additional Securities of this series may be issued from time to time hereafter; provided that any such additional Securities that are not fungible with this Security for U.S. federal income tax purposes will have a separate CUSIP, ISIN and other identifying number than this Security.
The Company may, at its option, redeem all or any part of this Security. If it chooses to do so, it shall mail or electronically deliver according to the procedures of DTC a notice of redemption (the “Redemption Notice”) to the Holder hereof (with a copy to the Trustee) not less than 15 days and not more than 60 days before the Redemption Date. The Redemption Price shall equal the greater of (i) 100% of the principal amount of this Security to be redeemed or (ii) the sum of the present values of the Remaining Scheduled Payments on the principal amount of this Security to be redeemed, discounted to the Redemption Date on a semiannual basis, assuming a 360-day year consisting of twelve 30-day months, at the Treasury Rate plus 30 basis points. The Redemption Price shall also include interest accrued to, but excluding, the Redemption Date on the principal balance of this Security to be redeemed.
“Treasury Rate” means, for any Redemption Date, the annual rate equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue equal to the Comparable Treasury Price, expressed as a percentage of its principal amount, for that Redemption Date. The yield of the Comparable Treasury Issue will be computed as of the second Business Day immediately preceding the date of the Redemption Notice.
“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent (defined below) that has a maturity comparable to the remaining maturity of this Security and that would be used in accordance with customary financial practice to price new issues of corporate debt securities with a maturity comparable to the remaining term of the Securities. The investment banks from which the Company will select a Quotation Agent are BofA Securities, Inc., Citigroup Global Markets Inc. and Morgan Stanley & Co. LLC, or their respective successors, or up to two other nationally recognized investment banking firms that are primary U.S. government securities dealers in New York City (each, a “Reference Treasury Dealer”). The Company will select one of the Reference Treasury Dealers to serve as its quotation agent (the “Quotation Agent”). If any of the firms referenced in the second

preceding sentence ceases to be a primary dealer of U.S. government securities in New York City, the Company shall appoint another nationally recognized investment banking firm that is a primary dealer as a substitute.
“Comparable Treasury Price” means, for any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations given to the Trustee by the Reference Treasury Dealers for that Redemption Date after excluding the highest and lowest of those Reference Treasury Dealer Quotations (or only one of the highest or lowest of the Reference Treasury Dealer Quotations if there are more than one), or (2) if the Trustee is given fewer than four Reference Treasury Dealer Quotations, the average of all those quotations.
“Reference Treasury Dealer Quotation” means, with respect to any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the Trustee by a Reference Treasury Dealer as of 3:30 p.m., New York time, on the second Business Day preceding the date of the Redemption Notice. The Trustee shall seek Reference Treasury Dealer Quotations in respect of any Redemption Date from each of the then-existing Reference Treasury Dealers.
“Remaining Scheduled Payments” means, with respect to the principal amount of each Security being redeemed, the remaining scheduled payments of principal and interest on that Security that would be due after the related Redemption Date but for the redemption. If, however, the Redemption Date is not an Interest Payment Date with respect to that Security, the amount of the next succeeding scheduled interest payment on that Security that would have been due will be deemed reduced by the amount of interest accrued on the Security to the Redemption Date.
On and after any Redemption Date, interest shall cease to accrue with respect to the Securities, or any portion of the Securities, called for redemption and for which the Redemption Price has been paid or made available for payment. On or prior to any Redemption Date, the Company shall deposit with the Paying Agent or the Trustee money sufficient to pay the Redemption Price on the Securities to be redeemed on such Redemption Date. If less than all of the Securities of this series are redeemed, the Trustee shall choose the Securities of this series to be redeemed by any method that it deems fair and appropriate, provided that if the Securities of this series are represented by one or more global Securities, interests in the Securities of this series will be selected for redemption by DTC in accordance with its standard procedures therefor.
Notwithstanding Section 1104 of the Indenture, the notice of any redemption referred to herein need not set forth the Redemption Price therefor but only the manner of calculation thereof. Promptly after the calculation of such Redemption Price, the Company shall give the Trustee notice thereof and the Trustee shall not be responsible for such calculation.
This Security is not repayable at the option of the Holder hereof and is not subject to the operation of any sinking fund.

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.
The provisions of Section 1402 and Section 1403 of the Indenture relating to defeasance and covenant defeasance, respectively, shall apply to this Security. Pursuant to Section 1404(5) and Section 1404(6) of the Indenture, any such defeasance or covenant defeasance shall be conditioned on receipt of an Opinion of Counsel relating to the federal income tax consequences of such defeasance or covenant defeasance.
The Company will not pay any Additional Amounts to Holders that are not U.S. persons (including any modification to the definition of such term) in respect of any tax, assessment or governmental charge.
The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of all Securities at the time Outstanding to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Outstanding Securities, to waive compliance by the Company with certain provisions of the Indenture, and contains provisions permitting the Holders of specified percentages in principal amount, in certain instances of the Outstanding Securities of individual series and in other instances of all Securities at the time Outstanding, to waive on behalf of all of the Holders of Securities of such individual series or of the Holders of all Securities at the time Outstanding, as the case may be, certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.
As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount, in certain instances of the Securities of this series at the time Outstanding and in other instances of all Outstanding Securities, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of not less than a majority in principal amount of Securities of this series at the time Outstanding or of all Outstanding Securities, as the case may be, a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for

the enforcement of any payment of principal hereof (and premium, if any) or interest hereon on or after the respective due dates expressed herein.
No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or make provision as provided in Article Fourteen of the Indenture for the payment of the amount of principal of (and premium, if any) and interest on this Security herein provided, and at the times, place and rate, and in the coin or currency, herein prescribed.
As provided in the Indenture and subject to certain limitations therein and herein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.
The Securities of this series are issuable only in registered form without coupons in minimum denominations of $2,000 and any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series of a different authorized denomination, as requested by the Holder surrendering the same.
No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.
Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.
All terms used in this Security that are defined in the Indenture shall have the meanings assigned to them in the Indenture.

This Security is one of the series designated on the face hereof. The Indenture does not limit the aggregate principal amount of the Securities or the Securities of this series that may be issued thereunder. Additional Securities of this series may be issued from time to time hereafter; provided that any such additional Securities that are not fungible with this Security for U.S. federal income tax purposes will have a separate CUSIP, ISIN and other identifying number than this Security.
The Company may not redeem all or any part of this Security prior to its maturity.
This Security is not repayable at the option of the Holder hereof and is not subject to the operation of any sinking fund.

The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof (and premium, if any) or interest hereon on or after the respective due dates expressed herein.

TRUSTEE’S CERTIFICATE OF AUTHENTICATION
This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

| THE BANK OF NEW YORK MELLON TRUST COMPANY, N.A., as Trustee
| By: |
|  | Authorized Signatory

Dated: _____________________

[REVERSE OF SECURITY]
This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Amended and Restated Indenture, dated as of May 1, 2001, as it may be supplemented from time to time (herein called the “Indenture”), between the Company (formerly known as United Technologies Corporation) and The Bank of New York Mellon Trust Company, N.A. (formerly The Bank of New York Trust Company, N.A.), as Trustee (successor to The Bank of New York) (herein called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the series of which this Security is a part), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof. The Indenture does not limit the aggregate principal amount of the Securities or the Securities of this series that may be issued thereunder. Additional Securities of this series may be issued from time to time hereafter; provided that any such additional Securities that are not fungible with this Security for U.S. federal income tax purposes will have a separate CUSIP, ISIN and other identifying number than this Security.
The Company may, at its option, redeem all or any part of this Security. If it chooses to do so, it shall mail or electronically deliver according to the procedures of DTC a notice of redemption (the “Redemption Notice”) to the Holder hereof (with a copy to the Trustee) not less than 15 days and not more than 60 days before the Redemption Date. If this Security is redeemed prior to September 15, 2022, the Redemption Price shall equal the greater of (i) 100% of the principal amount of this Security to be redeemed or (ii) the sum of the present values of the Remaining Scheduled Payments on the principal amount of this Security to be redeemed, assuming for such purpose that this Security matured on September 15, 2022, discounted to the Redemption Date on a semiannual basis, assuming a 360-day year consisting of twelve 30-day months, at the Treasury Rate plus 15 basis points. If this Security is redeemed on or after September 15, 2022, the Redemption Price shall be 100% of the principal amount of this Security to be redeemed. In each case, the Redemption Price shall also include interest accrued to, but excluding, the Redemption Date on the principal balance of this Security to be redeemed.
“Treasury Rate” means, for any Redemption Date, the annual rate equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue equal to the Comparable Treasury Price, expressed as a percentage of its principal amount, for that Redemption Date. The yield of the Comparable Treasury Issue will be computed as of the second Business Day immediately preceding the date of the Redemption Notice.
“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent (defined below) that has a maturity comparable to the remaining maturity of this Security (assuming, for this purpose, that this Security matured on September 15, 2022) and that would be used in accordance with customary financial practice to price new issues of corporate debt securities with a maturity comparable to the remaining term of the Securities. The investment banks from which the Company will select a Quotation Agent are BofA Securities, Inc., Citigroup Global Markets Inc. and Morgan Stanley & Co. LLC, or their respective successors, or up to two other nationally recognized investment banking firms that are primary U.S. government securities dealers in New York City (each, a “Reference Treasury Dealer”). The Company will select one of the Reference Treasury Dealers to serve as its quotation agent (the “Quotation Agent”). If any of the firms referenced in the second preceding sentence ceases to be a primary dealer of U.S. government securities in New York City, the Company shall appoint another nationally recognized investment banking firm that is a primary dealer as a substitute.

“Comparable Treasury Price” means, for any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations given to the Trustee by the Reference Treasury Dealers for that Redemption Date after excluding the highest and lowest of those Reference Treasury Dealer Quotations (or only one of the highest or lowest of the Reference Treasury Dealer Quotations if there are more than one), or (2) if the Trustee is given fewer than four Reference Treasury Dealer Quotations, the average of all those quotations.
“Reference Treasury Dealer Quotation” means, with respect to any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the Trustee by a Reference Treasury Dealer as of 3:30 p.m., New York time, on the second Business Day preceding the date of the Redemption Notice. The Trustee shall seek Reference Treasury Dealer Quotations in respect of any Redemption Date from each of the then-existing Reference Treasury Dealers.
“Remaining Scheduled Payments” means, with respect to the principal amount of each Security being redeemed, the remaining scheduled payments of principal and interest on that Security that would be due after the related Redemption Date but for the redemption, assuming for such purpose that this Security matured on September 15, 2022. If, however, the Redemption Date is not an Interest Payment Date with respect to that Security, the amount of the next succeeding scheduled interest payment on that Security that would have been due will be deemed reduced by the amount of interest accrued on the Security to the Redemption Date.
On and after any Redemption Date, interest shall cease to accrue with respect to the Securities, or any portion of the Securities, called for redemption and for which the Redemption Price has been paid or made available for payment. On or prior to any Redemption Date, the Company shall deposit with the Paying Agent or the Trustee money sufficient to pay the Redemption Price on the Securities to be redeemed on such Redemption Date. If less than all of the Securities of this series are redeemed, the Trustee shall choose the Securities of this series to be redeemed by any method that it deems fair and appropriate, provided that if the Securities of this series are represented by one or more global Securities, interests in the Securities of this series will be selected for redemption by DTC in accordance with its standard procedures therefor.

Notwithstanding Section 1104 of the Indenture, the notice of any redemption referred to herein need not set forth the Redemption Price therefor but only the manner of calculation thereof. Promptly after the calculation of such Redemption Price, the Company shall give the Trustee notice thereof and the Trustee shall not be responsible for such calculation.
This Security is not repayable at the option of the Holder hereof and is not subject to the operation of any sinking fund.
If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.
The provisions of Section 1402 and Section 1403 of the Indenture relating to defeasance and covenant defeasance, respectively, shall apply to this Security. Pursuant to Section 1404(5) and Section 1404(6) of the Indenture, any such defeasance or covenant defeasance shall be conditioned on receipt of an Opinion of Counsel relating to the federal income tax consequences of such defeasance or covenant defeasance.
The Company will not pay any Additional Amounts to Holders that are not U.S. persons (including any modification to the definition of such term) in respect of any tax, assessment or governmental charge.
The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of all Securities at the time Outstanding to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Outstanding Securities, to waive compliance by the Company with certain provisions of the Indenture, and contains provisions permitting the Holders of specified percentages in principal amount, in certain instances of the Outstanding Securities of individual series and in other instances of all Securities at the time Outstanding, to waive on behalf of all of the Holders of Securities of such individual series or of the Holders of all Securities at the time Outstanding, as the case may be, certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.
As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount, in certain instances of the Securities of this series at the time Outstanding and in other instances of all Outstanding Securities, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of not less than a majority in principal amount of Securities of this series at the time Outstanding or of all Outstanding Securities, as the case may be, a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof (and premium, if any) or interest hereon on or after the respective due dates expressed herein.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or make provision as provided in Article Fourteen of the Indenture for the payment of the amount of principal of (and premium, if any) and interest on this Security herein provided, and at the times, place and rate, and in the coin or currency, herein prescribed.
As provided in the Indenture and subject to certain limitations therein and herein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.
The Securities of this series are issuable only in registered form without coupons in minimum denominations of $2,000 and any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series of a different authorized denomination, as requested by the Holder surrendering the same.
No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.
Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

TRUSTEE’S CERTIFICATE OF AUTHENTICATION
This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

| THE BANK OF NEW YORK MELLON TRUST COMPANY, N.A., as Trustee
| By: |
|  | Authorized Signatory |

Dated: |  |

[REVERSE OF SECURITY]
This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Amended and Restated Indenture, dated as of May 1, 2001, as it may be supplemented from time to time (herein called the “Indenture”), between the Company (formerly known as United Technologies Corporation) and The Bank of New York Mellon Trust Company, N.A. (formerly The Bank of New York Trust Company, N.A.), as Trustee (successor to The Bank of New York) (herein called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the series of which this Security is a part), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof. The Indenture does not limit the aggregate principal amount of the Securities or the Securities of this series that may be issued thereunder. Additional Securities of this series may be issued from time to time hereafter; provided that any such additional Securities that are not fungible with this Security for U.S. federal income tax purposes will have a separate CUSIP, ISIN and other identifying number than this Security.
The Company may, at its option, redeem all or any part of this Security. If it chooses to do so, it shall mail or electronically deliver according to the procedures of DTC a notice of redemption (the “Redemption Notice”) to the Holder hereof (with a copy to the Trustee) not less than 15 days and not more than 60 days before the Redemption Date. If this Security is redeemed prior to September 15, 2022, the Redemption Price shall equal the greater of (i) 100% of the principal amount of this Security to be redeemed or (ii) the sum of the present values of the Remaining Scheduled Payments on the principal amount of this Security to be redeemed, assuming for such purpose that this Security matured on September 15, 2022, discounted to the Redemption Date on a semiannual basis, assuming a 360-day year consisting of twelve 30-day months, at the Treasury Rate plus 15 basis points. If this Security is redeemed on or after September 15, 2022, the Redemption Price shall be 100% of the principal amount of this Security to be redeemed. In each case, the Redemption Price shall also include interest accrued to, but excluding, the Redemption Date on the principal balance of this Security to be redeemed.
“Treasury Rate” means, for any Redemption Date, the annual rate equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue equal to the Comparable Treasury Price, expressed as a percentage of its principal amount, for that Redemption Date. The yield of the Comparable Treasury Issue will be computed as of the second Business Day immediately preceding the date of the Redemption Notice.
“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent (defined below) that has a maturity comparable to the remaining maturity of this Security (assuming, for this purpose, that this Security matured on September 15, 2022) and that would be used in accordance with customary financial practice to price new issues of corporate debt securities with a maturity comparable to the remaining term of the Securities. The investment banks from which the Company will select a Quotation Agent are BofA Securities, Inc., Citigroup Global Markets Inc. and Morgan Stanley & Co. LLC, or their

respective successors, or up to two other nationally recognized investment banking firms that are primary U.S. government securities dealers in New York City (each, a “Reference Treasury Dealer”). The Company will select one of the Reference Treasury Dealers to serve as its quotation agent (the “Quotation Agent”). If any of the firms referenced in the second preceding sentence ceases to be a primary dealer of U.S. government securities in New York City, the Company shall appoint another nationally recognized investment banking firm that is a primary dealer as a substitute.
“Comparable Treasury Price” means, for any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations given to the Trustee by the Reference Treasury Dealers for that Redemption Date after excluding the highest and lowest of those Reference Treasury Dealer Quotations (or only one of the highest or lowest of the Reference Treasury Dealer Quotations if there are more than one), or (2) if the Trustee is given fewer than four Reference Treasury Dealer Quotations, the average of all those quotations.
“Reference Treasury Dealer Quotation” means, with respect to any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the Trustee by a Reference Treasury Dealer as of 3:30 p.m., New York time, on the second Business Day preceding the date of the Redemption Notice. The Trustee shall seek Reference Treasury Dealer Quotations in respect of any Redemption Date from each of the then-existing Reference Treasury Dealers.
“Remaining Scheduled Payments” means, with respect to the principal amount of each Security being redeemed, the remaining scheduled payments of principal and interest on that Security that would be due after the related Redemption Date but for the redemption, assuming for such purpose that this Security matured on September 15, 2022. If, however, the Redemption Date is not an Interest Payment Date with respect to that Security, the amount of the next succeeding scheduled interest payment on that Security that would have been due will be deemed reduced by the amount of interest accrued on the Security to the Redemption Date.
On and after any Redemption Date, interest shall cease to accrue with respect to the Securities, or any portion of the Securities, called for redemption and for which the Redemption Price has been paid or made available for payment. On or prior to any Redemption Date, the Company shall deposit with the Paying Agent or the Trustee money sufficient to pay the Redemption Price on the Securities to be redeemed on such Redemption Date. If less than all of the Securities of this series are redeemed, the Trustee shall choose the Securities of this series to be redeemed by any method that it deems fair and appropriate, provided that if the Securities of this series are represented by one or more global Securities, interests in the Securities of this series will be selected for redemption by DTC in accordance with its standard procedures therefor.
Notwithstanding Section 1104 of the Indenture, the notice of any redemption referred to herein need not set forth the Redemption Price therefor but only the manner of calculation thereof. Promptly after the calculation of such Redemption Price, the Company shall give the Trustee notice thereof and the Trustee shall not be responsible for such calculation.

This Security is not repayable at the option of the Holder hereof and is not subject to the operation of any sinking fund.
If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.
The provisions of Section 1402 and Section 1403 of the Indenture relating to defeasance and covenant defeasance, respectively, shall apply to this Security. Pursuant to Section 1404(5) and Section 1404(6) of the Indenture, any such defeasance or covenant defeasance shall be conditioned on receipt of an Opinion of Counsel relating to the federal income tax consequences of such defeasance or covenant defeasance.
The Company will not pay any Additional Amounts to Holders that are not U.S. persons (including any modification to the definition of such term) in respect of any tax, assessment or governmental charge.
The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of all Securities at the time Outstanding to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Outstanding Securities, to waive compliance by the Company with certain provisions of the Indenture, and contains provisions permitting the Holders of specified percentages in principal amount, in certain instances of the Outstanding Securities of individual series and in other instances of all Securities at the time Outstanding, to waive on behalf of all of the Holders of Securities of such individual series or of the Holders of all Securities at the time Outstanding, as the case may be, certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.
As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount, in certain instances of the Securities of this series at the time Outstanding and in other instances of all Outstanding Securities, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of not less than a majority in principal amount of Securities of this series at the time Outstanding or of all Outstanding Securities, as the case may be, a direction inconsistent with such request, and shall have failed to

institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof (and premium, if any) or interest hereon on or after the respective due dates expressed herein.
No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or make provision as provided in Article Fourteen of the Indenture for the payment of the amount of principal of (and premium, if any) and interest on this Security herein provided, and at the times, place and rate, and in the coin or currency, herein prescribed.
As provided in the Indenture and subject to certain limitations therein and herein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.
The Securities of this series are issuable only in registered form without coupons in minimum denominations of $2,000 and any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series of a different authorized denomination, as requested by the Holder surrendering the same.
No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.
Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.
All terms used in this Security that are defined in the Indenture shall have the meanings assigned to them in the Indenture.

[REVERSE OF SECURITY]
This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Amended and Restated Indenture, dated as of May 1, 2001, as it may be supplemented from time to time (herein called the “Indenture”), between the Company (formerly known as United Technologies Corporation) and The Bank of New York Mellon Trust Company, N.A. (formerly The Bank of New York Trust Company, N.A.), as Trustee (successor to The Bank of New York) (herein called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the series of which this Security is a part), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof. The Indenture does not limit the aggregate principal amount of the Securities or the Securities of this series that may be issued thereunder. Additional Securities of this series may be issued from time to time hereafter; provided that any such additional Securities that are not fungible with this Security for U.S. federal income tax purposes will have a separate CUSIP, ISIN and other identifying number than this Security.
The Company may, at its option, redeem all or any part of this Security. If it chooses to do so, it shall mail or electronically deliver according to the procedures of DTC a notice of redemption (the “Redemption Notice”) to the Holder hereof (with a copy to the Trustee) not less than 15 days and not more than 60 days before the Redemption Date. [If this Security is redeemed prior to September 15, 2022, the Redemption Price shall equal the greater of (i) 100% of the principal amount of this Security to be redeemed or (ii) the sum of the present values of the Remaining Scheduled Payments on the principal amount of this Security to be redeemed, assuming for such purpose that this Security matured on September 15, 2022, discounted to the Redemption Date on a semiannual basis, assuming a 360-day year consisting of twelve 30-day months, at the Treasury Rate plus 15 basis points. If this Security is redeemed on or after September 15, 2022, the Redemption Price shall be 100% of the principal amount of this Security to be redeemed. In each case, the Redemption Price shall also include interest accrued to, but excluding, the Redemption Date on the principal balance of this Security to be redeemed.
“Treasury Rate” means, for any Redemption Date, the annual rate equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue equal to the Comparable Treasury Price, expressed as a percentage of its principal amount, for that Redemption Date. The yield of the Comparable Treasury Issue will be computed as of the second Business Day immediately preceding the date of the Redemption Notice.
“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent (defined below) that has a maturity comparable to the remaining maturity of this Security (assuming, for this purpose, that this Security matured on September 15, 2022) and that would be used in accordance with customary financial practice to price new issues of corporate debt securities with a maturity comparable to the remaining term of the Securities. The investment banks from which the Company will select a Quotation Agent are BofA Securities, Inc., Citigroup Global Markets Inc. and Morgan Stanley & Co. LLC, or their

respective successors, or up to two other nationally recognized investment banking firms that are primary U.S. government securities dealers in New York City (each, a “Reference Treasury Dealer”). The Company will select one of the Reference Treasury Dealers to serve as its quotation agent (the “Quotation Agent”). If any of the firms referenced in the second preceding sentence ceases to be a primary dealer of U.S. government securities in New York City, the Company shall appoint another nationally recognized investment banking firm that is a primary dealer as a substitute.
“Comparable Treasury Price” means, for any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations given to the Trustee by the Reference Treasury Dealers for that Redemption Date after excluding the highest and lowest of those Reference Treasury Dealer Quotations (or only one of the highest or lowest of the Reference Treasury Dealer Quotations if there are more than one), or (2) if the Trustee is given fewer than four Reference Treasury Dealer Quotations, the average of all those quotations.
“Reference Treasury Dealer Quotation” means, with respect to any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the Trustee by a Reference Treasury Dealer as of 3:30 p.m., New York time, on the second Business Day preceding the date of the Redemption Notice. The Trustee shall seek Reference Treasury Dealer Quotations in respect of any Redemption Date from each of the then-existing Reference Treasury Dealers.
“Remaining Scheduled Payments” means, with respect to the principal amount of each Security being redeemed, the remaining scheduled payments of principal and interest on that Security that would be due after the related Redemption Date but for the redemption, assuming for such purpose that this Security matured on September 15, 2022. If, however, the Redemption Date is not an Interest Payment Date with respect to that Security, the amount of the next succeeding scheduled interest payment on that Security that would have been due will be deemed reduced by the amount of interest accrued on the Security to the Redemption Date.
On and after any Redemption Date, interest shall cease to accrue with respect to the Securities, or any portion of the Securities, called for redemption and for which the Redemption Price has been paid or made available for payment. On or prior to any Redemption Date, the Company shall deposit with the Paying Agent or the Trustee money sufficient to pay the Redemption Price on the Securities to be redeemed on such Redemption Date. If less than all of the Securities of this series are redeemed, the Trustee shall choose the Securities of this series to be redeemed by any method that it deems fair and appropriate, provided that if the Securities of this series are represented by one or more global Securities, interests in the Securities of this series will be selected for redemption by DTC in accordance with its standard procedures therefor.
Notwithstanding Section 1104 of the Indenture, the notice of any redemption referred to herein need not set forth the Redemption Price therefor but only the manner of calculation thereof. Promptly after the calculation of such Redemption Price, the Company shall give the Trustee notice thereof and the Trustee shall not be responsible for such calculation.

This Security is not repayable at the option of the Holder hereof and is not subject to the operation of any sinking fund.
If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.
The provisions of Section 1402 and Section 1403 of the Indenture relating to defeasance and covenant defeasance, respectively, shall apply to this Security. Pursuant to Section 1404(5) and Section 1404(6) of the Indenture, any such defeasance or covenant defeasance shall be conditioned on receipt of an Opinion of Counsel relating to the federal income tax consequences of such defeasance or covenant defeasance.
The Company will not pay any Additional Amounts to Holders that are not U.S. persons (including any modification to the definition of such term) in respect of any tax, assessment or governmental charge.
The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of all Securities at the time Outstanding to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Outstanding Securities, to waive compliance by the Company with certain provisions of the Indenture, and contains provisions permitting the Holders of specified percentages in principal amount, in certain instances of the Outstanding Securities of individual series and in other instances of all Securities at the time Outstanding, to waive on behalf of all of the Holders of Securities of such individual series or of the Holders of all Securities at the time Outstanding, as the case may be, certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.
As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount, in certain instances of the Securities of this series at the time Outstanding and in other instances of all Outstanding Securities, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of not less than a majority in principal amount of Securities of this series at the time Outstanding or of all Outstanding Securities, as the case may be, a direction inconsistent with such request, and shall have failed to

institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof (and premium, if any) or interest hereon on or after the respective due dates expressed herein.
No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or make provision as provided in Article Fourteen of the Indenture for the payment of the amount of principal of (and premium, if any) and interest on this Security herein provided, and at the times, place and rate, and in the coin or currency, herein prescribed.
As provided in the Indenture and subject to certain limitations therein and herein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.
The Securities of this series are issuable only in registered form without coupons in minimum denominations of $2,000 and any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series of a different authorized denomination, as requested by the Holder surrendering the same.
No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.
Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Amended and Restated Indenture, dated as of May 1, 2001, as it may be supplemented from time to time (herein called the “Indenture”), between the Company (formerly known as United Technologies Corporation) and The Bank of New York Mellon Trust Company, N.A. (formerly The Bank of New York Trust Company, N.A.), as Trustee (successor to The Bank of New York) (herein called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the series of which this Security is a part), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof. The Indenture does not limit the aggregate principal amount of the Securities or the Securities of this series that may be issued thereunder. Additional Securities of this series may be issued from time to time hereafter; provided that any such additional Securities that are not fungible with this Security for U.S. federal income tax purposes will have a separate CUSIP, ISIN and other identifying number than this Security.
The Company may, at its option, redeem all or any part of this Security. If it chooses to do so, it shall mail or electronically deliver according to the procedures of DTC a notice of redemption (the “Redemption Notice”) to the Holder hereof (with a copy to the Trustee) not less than 15 days and not more than 60 days before the Redemption Date. If this Security is redeemed prior to September 15, 2024, the Redemption Price shall equal the greater of (i) 100% of the principal amount of this Security to be redeemed or (ii) the sum of the present values of the Remaining Scheduled Payments on the principal amount of this Security to be redeemed, assuming for such purpose that this Security matured on September 15, 2024, discounted to the Redemption Date on a semiannual basis, assuming a 360-day year consisting of twelve 30-day months, at the Treasury Rate plus 15 basis points. If this Security is redeemed on or after September 15, 2024, the Redemption Price shall be 100% of the principal amount of this Security to be redeemed. In each case, the Redemption Price shall also include interest accrued to, but excluding, the Redemption Date on the principal balance of this Security to be redeemed.
“Treasury Rate” means, for any Redemption Date, the annual rate equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue equal to the Comparable Treasury Price, expressed as a percentage of its principal amount, for that Redemption Date. The yield of the Comparable Treasury Issue will be computed as of the second Business Day immediately preceding the date of the Redemption Notice.
“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent (defined below) that has a maturity comparable to the remaining maturity of this Security (assuming, for this purpose, that this Security matured on September 15, 2024) and that would be used in accordance with customary financial practice to price new issues of corporate debt securities with a maturity comparable to the remaining term of the Securities. The investment banks from which the Company will select a Quotation Agent are BofA Securities, Inc., Citigroup Global Markets Inc. and Morgan Stanley & Co. LLC, or their

respective successors, or up to two other nationally recognized investment banking firms that are primary U.S. government securities dealers in New York City (each, a “Reference Treasury Dealer”). The Company will select one of the Reference Treasury Dealers to serve as its quotation agent (the “Quotation Agent”).

“Comparable Treasury Price” means, for any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations given to the Trustee by the Reference Treasury Dealers for that Redemption Date after excluding the highest and lowest of those Reference Treasury Dealer Quotations (or only one of the highest or lowest of the Reference Treasury Dealer Quotations if there are more than one), or (2) if the Trustee is given fewer than four Reference Treasury Dealer Quotations, the average of all those quotations.
“Reference Treasury Dealer Quotation” means, with respect to any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the Trustee by a Reference Treasury Dealer as of 3:30 p.m., New York time, on the second Business Day preceding the date of the Redemption Notice. The Trustee shall seek Reference Treasury Dealer Quotations in respect of any Redemption Date from each of the then-existing Reference Treasury Dealers.
“Remaining Scheduled Payments” means, with respect to the principal amount of each Security being redeemed, the remaining scheduled payments of principal and interest on that Security that would be due after the related Redemption Date but for the redemption, assuming for such purpose that this Security matured on September 15, 2024. If, however, the Redemption Date is not an Interest Payment Date with respect to that Security, the amount of the next succeeding scheduled interest payment on that Security that would have been due will be deemed reduced by the amount of interest accrued on the Security to the Redemption Date.
On and after any Redemption Date, interest shall cease to accrue with respect to the Securities, or any portion of the Securities, called for redemption and for which the Redemption Price has been paid or made available for payment. On or prior to any Redemption Date, the Company shall deposit with the Paying Agent or the Trustee money sufficient to pay the Redemption Price on the Securities to be redeemed on such Redemption Date. If less than all of the Securities of this series are redeemed, the Trustee shall choose the Securities of this series to be redeemed by any method that it deems fair and appropriate, provided that if the Securities of this series are represented by one or more global Securities, interests in the Securities of this series will be selected for redemption by DTC in accordance with its standard procedures therefor.
Notwithstanding Section 1104 of the Indenture, the notice of any redemption referred to herein need not set forth the Redemption Price therefor but only the manner of calculation thereof. Promptly after the calculation of such Redemption Price, the Company shall give the Trustee notice thereof and the Trustee shall not be responsible for such calculation.

This Security is not repayable at the option of the Holder hereof and is not subject to the operation of any sinking fund.
If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.
The provisions of Section 1402 and Section 1403 of the Indenture relating to defeasance and covenant defeasance, respectively, shall apply to this Security.

The Company will not pay any Additional Amounts to Holders that are not U.S. persons (including any modification to the definition of such term) in respect of any tax, assessment or governmental charge.
The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of all Securities at the time Outstanding to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Outstanding Securities, to waive compliance by the Company with certain provisions of the Indenture, and contains provisions permitting the Holders of specified percentages in principal amount, in certain instances of the Outstanding Securities of individual series and in other instances of all Securities at the time Outstanding, to waive on behalf of all of the Holders of Securities of such individual series or of the Holders of all Securities at the time Outstanding, as the case may be, certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

registered assigns, the principal sum of TWO MILLION, THREE HUNDRED AND SIXTY-THREE THOUSAND DOLLARS ($2,363,000) on December 15, 2024, and to pay interest thereon (computed on the basis of a 360-day year comprised of twelve 30-day months) from December 15, 2019 or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semiannually in arrears on June 15 and December 15 of each year, and on the maturity date, commencing on June 15, 2020, at the rate of 3.150% per annum, until the principal hereof is paid or made available for payment. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the date that is fifteen calendar days prior to the scheduled Interest Payment Date, regardless of whether such date is a Business Day; provided that if this Security is held by a securities depositary in book-entry form, such date shall be the close of business on the Business Day immediately preceding the Interest Payment Date (the “Regular Record Date”); provided, that interest payable on the maturity date or any Redemption Date will be payable to the Person to whom the principal of this Security is payable.

TRUSTEE’S CERTIFICATE OF AUTHENTICATION
This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

| THE BANK OF NEW YORK MELLON TRUST COMPANY, N.A., as Trustee
| By: |
|  | Authorized Signatory

Dated: |  |

[REVERSE OF SECURITY]
This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Amended and Restated Indenture, dated as of May 1, 2001, as it may be supplemented from time to time (herein called the “Indenture”), between the Company (formerly known as United Technologies Corporation) and The Bank of New York Mellon Trust Company, N.A. (formerly The Bank of New York Trust Company, N.A.), as Trustee (successor to The Bank of New York) (herein called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the series of which this Security is a part), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof. The Indenture does not limit the aggregate principal amount of the Securities or the Securities of this series that may be issued thereunder. Additional Securities of this series may be issued from time to time hereafter; provided that any such additional Securities that are not fungible with this Security for U.S. federal income tax purposes will have a separate CUSIP, ISIN and other identifying number than this Security.
The Company may, at its option, redeem all or any part of this Security. If it chooses to do so, it shall mail or electronically deliver according to the procedures of DTC a notice of redemption (the “Redemption Notice”) to the Holder hereof (with a copy to the Trustee) not less than 15 days and not more than 60 days before the Redemption Date. If this Security is redeemed prior to September 15, 2024, the Redemption Price shall equal the greater of (i) 100% of the principal amount of this Security to be redeemed or (ii) the sum of the present values of the Remaining Scheduled Payments on the principal amount of this Security to be redeemed, assuming for such purpose that this Security matured on September 15, 2024, discounted to the Redemption Date on a semiannual basis, assuming a 360-day year consisting of twelve 30-day months, at the Treasury Rate plus 15 basis points. If this Security is redeemed on or after September 15, 2024, the Redemption Price shall be 100% of the principal amount of this Security to be redeemed. In each case, the Redemption Price shall also include interest accrued to, but excluding, the Redemption Date on the principal balance of this Security to be redeemed.
“Treasury Rate” means, for any Redemption Date, the annual rate equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue equal to the Comparable Treasury Price, expressed as a percentage of its principal amount, for that Redemption Date. The yield of the Comparable Treasury Issue will be computed as of the second Business Day immediately preceding the date of the Redemption Notice.
“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent (defined below) that has a maturity comparable to the remaining maturity of this Security (assuming, for this purpose, that this Security matured on September 15, 2024) and that would be used in accordance with customary financial practice to price new issues of corporate debt securities with a maturity comparable to the remaining term of the Securities. The investment banks from which the Company will select a Quotation Agent are BofA Securities, Inc., Citigroup Global Markets Inc. and Morgan Stanley & Co. LLC, or their

respective successors, or up to two other nationally recognized investment banking firms that are primary U.S. government securities dealers in New York City (each, a “Reference Treasury Dealer”). The Company will select one of the Reference Treasury Dealers to serve as its quotation agent (the “Quotation Agent”). If any of the firms referenced in the second preceding sentence ceases to be a primary dealer of U.S. government securities in New York City, the Company shall appoint another nationally recognized investment banking firm that is a primary dealer as a substitute.
“Comparable Treasury Price” means, for any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations given to the Trustee by the Reference Treasury Dealers for that Redemption Date after excluding the highest and lowest of those Reference Treasury Dealer Quotations (or only one of the highest or lowest of the Reference Treasury Dealer Quotations if there are more than one), or (2) if the Trustee is given fewer than four Reference Treasury Dealer Quotations, the average of all those quotations.
“Reference Treasury Dealer Quotation” means, with respect to any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the Trustee by a Reference Treasury Dealer as of 3:30 p.m., New York time, on the second Business Day preceding the date of the Redemption Notice. The Trustee shall seek Reference Treasury Dealer Quotations in respect of any Redemption Date from each of the then-existing Reference Treasury Dealers.
“Remaining Scheduled Payments” means, with respect to the principal amount of each Security being redeemed, the remaining scheduled payments of principal and interest on that Security that would be due after the related Redemption Date but for the redemption, assuming for such purpose that this Security matured on September 15, 2024. If, however, the Redemption Date is not an Interest Payment Date with respect to that Security, the amount of the next succeeding scheduled interest payment on that Security that would have been due will be deemed reduced by the amount of interest accrued on the Security to the Redemption Date.
On and after any Redemption Date, interest shall cease to accrue with respect to the Securities, or any portion of the Securities, called for redemption and for which the Redemption Price has been paid or made available for payment. On or prior to any Redemption Date, the Company shall deposit with the Paying Agent or the Trustee money sufficient to pay the Redemption Price on the Securities to be redeemed on such Redemption Date. If less than all of the Securities of this series are redeemed, the Trustee shall choose the Securities of this series to be redeemed by any method that it deems fair and appropriate, provided that if the Securities of this series are represented by one or more global Securities, interests in the Securities of this series will be selected for redemption by DTC in accordance with its standard procedures therefor.
Notwithstanding Section 1104 of the Indenture, the notice of any redemption referred to herein need not set forth the Redemption Price therefor but only the manner of calculation thereof. Promptly after the calculation of such Redemption Price, the Company shall give the Trustee notice thereof and the Trustee shall not be responsible for such calculation.

This Security is not repayable at the option of the Holder hereof and is not subject to the operation of any sinking fund.
If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.
The provisions of Section 1402 and Section 1403 of the Indenture relating to defeasance and covenant defeasance, respectively, shall apply to this Security. Pursuant to Section 1404(5) and Section 1404(6) of the Indenture, any such defeasance or covenant defeasance shall be conditioned on receipt of an Opinion of Counsel relating to the federal income tax consequences of such defeasance or covenant defeasance.
The Company will not pay any Additional Amounts to Holders that are not U.S. persons (including any modification to the definition of such term) in respect of any tax, assessment or governmental charge.
The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of all Securities at the time Outstanding to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Outstanding Securities, to waive compliance by the Company with certain provisions of the Indenture, and contains provisions permitting the Holders of specified percentages in principal amount, in certain instances of the Outstanding Securities of individual series and in other instances of all Securities at the time Outstanding, to waive on behalf of all of the Holders of Securities of such individual series or of the Holders of all Securities at the time Outstanding, as the case may be, certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.
As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount, in certain instances of the Securities of this series at the time Outstanding and in other instances of all Outstanding Securities, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of not less than a majority in principal amount of Securities of this series at the time Outstanding or of all Outstanding Securities, as the case may be, a direction inconsistent with such request, and shall have failed to

institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof (and premium, if any) or interest hereon on or after the respective due dates expressed herein.
No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or make provision as provided in Article Fourteen of the Indenture for the payment of the amount of principal of (and premium, if any) and interest on this Security herein provided, and at the times, place and rate, and in the coin or currency, herein prescribed.
As provided in the Indenture and subject to certain limitations therein and herein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.
The Securities of this series are issuable only in registered form without coupons in minimum denominations of $2,000 and any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series of a different authorized denomination, as requested by the Holder surrendering the same.
No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.
Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

TRUSTEE’S CERTIFICATE OF AUTHENTICATION
This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

| THE BANK OF NEW YORK MELLON TRUST COMPANY, N.A., as Trustee
| By: |
|  | Authorized Signatory

Dated: |  |

[REVERSE OF SECURITY]
This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Amended and Restated Indenture, dated as of May 1, 2001, as it may be supplemented from time to time (herein called the “Indenture”), between the Company (formerly known as United Technologies Corporation) and The Bank of New York Mellon Trust Company, N.A. (formerly The Bank of New York Trust Company, N.A.), as Trustee (successor to The Bank of New York) (herein called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the series of which this Security is a part), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof. The Indenture does not limit the aggregate principal amount of the Securities or the Securities of this series that may be issued thereunder. Additional Securities of this series may be issued from time to time hereafter; provided that any such additional Securities that are not fungible with this Security for U.S. federal income tax purposes will have a separate CUSIP, ISIN and other identifying number than this Security.
The Company may, at its option, redeem all or any part of this Security. If it chooses to do so, it shall mail or electronically deliver according to the procedures of DTC a notice of redemption (the “Redemption Notice”) to the Holder hereof (with a copy to the Trustee) not less than 15 days and not more than 60 days before the Redemption Date. The Redemption Price shall equal the greater of (i) 100% of the principal amount of this Security to be redeemed or (ii) the sum of the present values of the Remaining Scheduled Payments on the principal amount of this Security to be redeemed, discounted to the Redemption Date on a semiannual basis, assuming a 360-day year consisting of twelve 30-day months, at the Treasury Rate plus 15 basis points. The Redemption Price shall also include interest accrued to, but excluding, the Redemption Date on the principal balance of this Security to be redeemed.
“Treasury Rate” means, for any Redemption Date, the annual rate equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue equal to the Comparable Treasury Price, expressed as a percentage of its principal amount, for that Redemption Date. The yield of the Comparable Treasury Issue will be computed as of the second Business Day immediately preceding the date of the Redemption Notice.
“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent (defined below) that has a maturity comparable to the remaining maturity of this Security and that would be used in accordance with customary financial practice to price new issues of corporate debt securities with a maturity comparable to the remaining term of the Securities. The investment banks from which the Company will select a Quotation Agent are BofA Securities, Inc., Citigroup Global Markets Inc. and Morgan Stanley & Co. LLC, or their respective successors, or up to two other nationally recognized investment banking firms that are primary U.S. government securities dealers in New York City (each, a “Reference Treasury Dealer”). The Company will select one of the Reference Treasury Dealers to serve as its quotation agent (the “Quotation Agent”). If any of the firms referenced in the second

preceding sentence ceases to be a primary dealer of U.S. government securities in New York City, the Company shall appoint another nationally recognized investment banking firm that is a primary dealer as a substitute.
“Comparable Treasury Price” means, for any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations given to the Trustee by the Reference Treasury Dealers for that Redemption Date after excluding the highest and lowest of those Reference Treasury Dealer Quotations (or only one of the highest or lowest of the Reference Treasury Dealer Quotations if there are more than one), or (2) if the Trustee is given fewer than four Reference Treasury Dealer Quotations, the average of all those quotations.
“Reference Treasury Dealer Quotation” means, with respect to any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the Trustee by a Reference Treasury Dealer as of 3:30 p.m., New York time, on the second Business Day preceding the date of the Redemption Notice. The Trustee shall seek Reference Treasury Dealer Quotations in respect of any Redemption Date from each of the then-existing Reference Treasury Dealers.
“Remaining Scheduled Payments” means, with respect to the principal amount of each Security being redeemed, the remaining scheduled payments of principal and interest on that Security that would be due after the related Redemption Date but for the redemption. If, however, the Redemption Date is not an Interest Payment Date with respect to that Security, the amount of the next succeeding scheduled interest payment on that Security that would have been due will be deemed reduced by the amount of interest accrued on the Security to the Redemption Date.
On and after any Redemption Date, interest shall cease to accrue with respect to the Securities, or any portion of the Securities, called for redemption and for which the Redemption Price has been paid or made available for payment. On or prior to any Redemption Date, the Company shall deposit with the Paying Agent or the Trustee money sufficient to pay the Redemption Price on the Securities to be redeemed on such Redemption Date. If less than all of the Securities of this series are redeemed, the Trustee shall choose the Securities of this series to be redeemed by any method that it deems fair and appropriate, provided that if the Securities of this series are represented by one or more global Securities, interests in the Securities of this series will be selected for redemption by DTC in accordance with its standard procedures therefor.
Notwithstanding Section 1104 of the Indenture, the notice of any redemption referred to herein need not set forth the Redemption Price therefor but only the manner of calculation thereof. Promptly after the calculation of such Redemption Price, the Company shall give the Trustee notice thereof and the Trustee shall not be responsible for such calculation.
This Security is not repayable at the option of the Holder hereof and is not subject to the operation of any sinking fund.

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.
The provisions of Section 1402 and Section 1403 of the Indenture relating to defeasance and covenant defeasance, respectively, shall apply to this Security. Pursuant to Section 1404(5) and Section 1404(6) of the Indenture, any such defeasance or covenant defeasance shall be conditioned on receipt of an Opinion of Counsel relating to the federal income tax consequences of such defeasance or covenant defeasance.
The Company will not pay any Additional Amounts to Holders that are not U.S. persons (including any modification to the definition of such term) in respect of any tax, assessment or governmental charge.
The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of all Securities at the time Outstanding to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Outstanding Securities, to waive compliance by the Company with certain provisions of the Indenture, and contains provisions permitting the Holders of specified percentages in principal amount, in certain instances of the Outstanding Securities of individual series and in other instances of all Securities at the time Outstanding, to waive on behalf of all of the Holders of Securities of such individual series or of the Holders of all Securities at the time Outstanding, as the case may be, certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.
As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount, in certain instances of the Securities of this series at the time Outstanding and in other instances of all Outstanding Securities, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of not less than a majority in principal amount of Securities of this series at the time Outstanding or of all Outstanding Securities, as the case may be, a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for

the enforcement of any payment of principal hereof (and premium, if any) or interest hereon on or after the respective due dates expressed herein.
No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or make provision as provided in Article Fourteen of the Indenture for the payment of the amount of principal of (and premium, if any) and interest on this Security herein provided, and at the times, place and rate, and in the coin or currency, herein prescribed.
As provided in the Indenture and subject to certain limitations therein and herein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.
The Securities of this series are issuable only in registered form without coupons in minimum denominations of $2,000 and any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series of a different authorized denomination, as requested by the Holder surrendering the same.
No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.
Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.
All terms used in this Security that are defined in the Indenture shall have the meanings assigned to them in the Indenture.

If it chooses to do so, it shall mail or electronically deliver according to the procedures of DTC a notice of redemption (the “Redemption Notice”) to the Holder hereof (with a copy to the Trustee) not less than 15 days and not more than 60 days before the Redemption Date. The Redemption Price shall equal the greater of (i) 100% of the principal amount of this Security to be redeemed or (ii) the sum of the present values of the Remaining Scheduled Payments on the principal amount of this Security to be redeemed, discounted to the Redemption Date on a semiannual basis, assuming a 360-day year consisting of twelve 30-day months, at the Treasury Rate plus 15 basis points. The Redemption Price shall also include interest accrued to, but excluding, the Redemption Date on the principal balance of this Security to be redeemed.
“Treasury Rate” means, for any Redemption Date, the annual rate equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue equal to the Comparable Treasury Price, expressed as a percentage of its principal amount, for that Redemption Date. The yield of the Comparable Treasury Issue will be computed as of the second Business Day immediately preceding the date of the Redemption Notice.
“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent (defined below) that has a maturity comparable to the remaining maturity of this Security and that would be used in accordance with customary financial practice to price new issues of corporate debt securities with a maturity comparable to the remaining term of the Securities. The investment banks from which the Company will select a Quotation Agent are BofA Securities, Inc., Citigroup Global Markets Inc. and Morgan Stanley & Co. LLC, or their respective successors, or up to two other nationally recognized investment banking firms that are primary U.S. government securities dealers in New York City (each, a “Reference Treasury Dealer”). The Company will select one of the Reference Treasury Dealers to serve as its quotation agent (the “Quotation Agent”). If any of the firms referenced in the second

preceding sentence ceases to be a primary dealer of U.S. government securities in New York City, the Company shall appoint another nationally recognized investment banking firm that is a primary dealer as a substitute.
“Comparable Treasury Price” means, for any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations given to the Trustee by the Reference Treasury Dealers for that Redemption Date after excluding the highest and lowest of those Reference Treasury Dealer Quotations (or only one of the highest or lowest of the Reference Treasury Dealer Quotations if there are more than one), or (2) if the Trustee is given fewer than four Reference Treasury Dealer Quotations, the average of all those quotations.
“Reference Treasury Dealer Quotation” means, with respect to any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the Trustee by a Reference Treasury Dealer as of 3:30 p.m., New York time, on the second Business Day preceding the date of the Redemption Notice. The Trustee shall seek Reference Treasury Dealer Quotations in respect of any Redemption Date from each of the then-existing Reference Treasury Dealers.
“Remaining Scheduled Payments” means, with respect to the principal amount of each Security being redeemed, the remaining scheduled payments of principal and interest on that Security that would be due after the related Redemption Date but for the redemption. If, however, the Redemption Date is not an Interest Payment Date with respect to that Security, the amount of the next succeeding scheduled interest payment on that Security that would have been due will be deemed reduced by the amount of interest accrued on the Security to the Redemption Date.
On and after any Redemption Date, interest shall cease to accrue with respect to the Securities, or any portion of the Securities, called for redemption and for which the Redemption Price has been paid or made available for payment. On or prior to any Redemption Date, the Company shall deposit with the Paying Agent or the Trustee money sufficient to pay the Redemption Price on the Securities to be redeemed on such Redemption Date. If less than all of the Securities of this series are redeemed, the Trustee shall choose the Securities of this series to be redeemed by any method that it deems fair and appropriate, provided that if the Securities of this series are represented by one or more global Securities, interests in the Securities of this series will be selected for redemption by DTC in accordance with its standard procedures therefor.
Notwithstanding Section 1104 of the Indenture, the notice of any redemption referred to herein need not set forth the Redemption Price therefor but only the manner of calculation thereof. Promptly after the calculation of such Redemption Price, the Company shall give the Trustee notice thereof and the Trustee shall not be responsible for such calculation.
This Security is not repayable at the option of the Holder hereof and is not subject to the operation of any sinking fund.

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.
The provisions of Section 1402 and Section 1403 of the Indenture relating to defeasance and covenant defeasance, respectively, shall apply to this Security. Pursuant to Section 1404(5) and Section 1404(6) of the Indenture, any such defeasance or covenant defeasance shall be conditioned on receipt of an Opinion of Counsel relating to the federal income tax consequences of such defeasance or covenant defeasance.
The Company will not pay any Additional Amounts to Holders that are not U.S. persons (including any modification to the definition of such term) in respect of any tax, assessment or governmental charge.
The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of all Securities at the time Outstanding to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Outstanding Securities, to waive compliance by the Company with certain provisions of the Indenture, and contains provisions permitting the Holders of specified percentages in principal amount, in certain instances of the Outstanding Securities of individual series and in other instances of all Securities at the time Outstanding, to waive on behalf of all of the Holders of Securities of such individual series or of the Holders of all Securities at the time Outstanding, as the case may be, certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.
As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount, in certain instances of the Securities of this series at the time Outstanding and in other instances of all Outstanding Securities, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of not less than a majority in principal amount of Securities of this series at the time Outstanding or of all Outstanding Securities, as the case may be, a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for

the enforcement of any payment of principal hereof (and premium, if any) or interest hereon on or after the respective due dates expressed herein.
No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or make provision as provided in Article Fourteen of the Indenture for the payment of the amount of principal of (and premium, if any) and interest on this Security herein provided, and at the times, place and rate, and in the coin or currency, herein prescribed.
As provided in the Indenture and subject to certain limitations therein and herein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series of a different authorized denomination, as requested by the Holder surrendering the same.
No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.
Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

[REVERSE OF SECURITY]
This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Amended and Restated Indenture, dated as of May 1, 2001, as it may be supplemented from time to time (herein called the “Indenture”), between the Company (formerly known as United Technologies Corporation) and The Bank of New York Mellon Trust Company, N.A. (formerly The Bank of New York Trust Company, N.A.), as Trustee (successor to The Bank of New York) (herein called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the series of which this Security is a part), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof. The Indenture does not limit the aggregate principal amount of the Securities or the Securities of this series that may be issued thereunder. Additional Securities of this series may be issued from time to time hereafter; provided that any such additional Securities that are not fungible with this Security for U.S. federal income tax purposes will have a separate CUSIP, ISIN and other identifying number than this Security.
The Company may, at its option, redeem all or any part of this Security. If it chooses to do so, it shall mail or electronically deliver according to the procedures of DTC a notice of redemption (the “Redemption Notice”) to the Holder hereof (with a copy to the Trustee) not less than 15 days and not more than 60 days before the Redemption Date. The Redemption Price shall equal the greater of (i) 100% of the principal amount of this Security to be redeemed or (ii) the sum of the present values of the Remaining Scheduled Payments on the principal amount of this Security to be redeemed, discounted to the Redemption Date on a semiannual basis, assuming a 360-day year consisting of twelve 30-day months, at the Treasury Rate plus 25 basis points. The Redemption Price shall also include interest accrued to, but excluding, the Redemption Date on the principal balance of this Security to be redeemed.
“Treasury Rate” means, for any Redemption Date, the annual rate equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue equal to the Comparable Treasury Price, expressed as a percentage of its principal amount, for that Redemption Date. The yield of the Comparable Treasury Issue will be computed as of the second Business Day immediately preceding the date of the Redemption Notice.
“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent (defined below) that has a maturity comparable to the remaining maturity of this Security and that would be used in accordance with customary financial practice to price new issues of corporate debt securities with a maturity comparable to the remaining term of the Securities. The investment banks from which the Company will select a Quotation Agent are BofA Securities, Inc., Citigroup Global Markets Inc. and Morgan Stanley & Co. LLC, or their respective successors, or up to two other nationally recognized investment banking firms that are primary U.S. government securities dealers in New York City (each, a “Reference Treasury Dealer”). The Company will select one of the Reference Treasury Dealers to serve as its quotation agent (the “Quotation Agent”). If any of the firms referenced in the second

preceding sentence ceases to be a primary dealer of U.S. government securities in New York City, the Company shall appoint another nationally recognized investment banking firm that is a primary dealer as a substitute.
“Comparable Treasury Price” means, for any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations given to the Trustee by the Reference Treasury Dealers for that Redemption Date after excluding the highest and lowest of those Reference Treasury Dealer Quotations (or only one of the highest or lowest of the Reference Treasury Dealer Quotations if there are more than one), or (2) if the Trustee is given fewer than four Reference Treasury Dealer Quotations, the average of all those quotations.
“Reference Treasury Dealer Quotation” means, with respect to any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the Trustee by a Reference Treasury Dealer as of 3:30 p.m., New York time, on the second Business Day preceding the date of the Redemption Notice. The Trustee shall seek Reference Treasury Dealer Quotations in respect of any Redemption Date from each of the then-existing Reference Treasury Dealers.
“Remaining Scheduled Payments” means, with respect to the principal amount of each Security being redeemed, the remaining scheduled payments of principal and interest on that Security that would be due after the related Redemption Date but for the redemption. If, however, the Redemption Date is not an Interest Payment Date with respect to that Security, the amount of the next succeeding scheduled interest payment on that Security that would have been due will be deemed reduced by the amount of interest accrued on the Security to the Redemption Date.
On and after any Redemption Date, interest shall cease to accrue with respect to the Securities, or any portion of the Securities, called for redemption and for which the Redemption Price has been paid or made available for payment. On or prior to any Redemption Date, the Company shall deposit with the Paying Agent or the Trustee money sufficient to pay the Redemption Price on the Securities to be redeemed on such Redemption Date. If less than all of the Securities of this series are redeemed, the Trustee shall choose the Securities of this series to be redeemed by any method that it deems fair and appropriate, provided that if the Securities of this series are represented by one or more global Securities, interests in the Securities of this series will be selected for redemption by DTC in accordance with its standard procedures therefor.
Notwithstanding Section 1104 of the Indenture, the notice of any redemption referred to herein need not set forth the Redemption Price therefor but only the manner of calculation thereof. Promptly after the calculation of such Redemption Price, the Company shall give the Trustee notice thereof and the Trustee shall not be responsible for such calculation.
This Security is not repayable at the option of the Holder hereof and is not subject to the operation of any sinking fund.

Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

The foregoing shall not apply to any suit instituted by the Holder of this Security for

the enforcement of any payment of principal hereof (and premium, if any) or interest hereon on or after the respective due dates expressed herein.
No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or make provision as provided in Article Fourteen of the Indenture for the payment of the amount of principal of (and premium, if any) and interest on this Security herein provided, and at the times, place and rate, and in the coin or currency, herein prescribed.

TRUSTEE’S CERTIFICATE OF AUTHENTICATION
This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

| THE BANK OF NEW YORK MELLON TRUST COMPANY, N.A., as Trustee
| By: |
|  | Authorized Signatory

Dated: _____________________

[REVERSE OF SECURITY]
This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Amended and Restated Indenture, dated as of May 1, 2001, as it may be supplemented from time to time (herein called the “Indenture”), between the Company (formerly known as United Technologies Corporation) and The Bank of New York Mellon Trust Company, N.A. (formerly The Bank of New York Trust Company, N.A.), as Trustee (successor to The Bank of New York) (herein called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the series of which this Security is a part), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof. The Indenture does not limit the aggregate principal amount of the Securities or the Securities of this series that may be issued thereunder. Additional Securities of this series may be issued from time to time hereafter; provided that any such additional Securities that are not fungible with this Security for U.S. federal income tax purposes will have a separate CUSIP, ISIN and other identifying number than this Security.
The Company may, at its option, redeem all or any part of this Security. If it chooses to do so, it shall mail or electronically deliver according to the procedures of DTC a notice of redemption (the “Redemption Notice”) to the Holder hereof (with a copy to the Trustee) not less than 15 days and not more than 60 days before the Redemption Date. The Redemption Price shall equal the greater of (i) 100% of the principal amount of this Security to be redeemed or (ii) the sum of the present values of the Remaining Scheduled Payments on the principal amount of this Security to be redeemed, discounted to the Redemption Date on a semiannual basis, assuming a 360-day year consisting of twelve 30-day months, at the Treasury Rate plus 25 basis points. The Redemption Price shall also include interest accrued to, but excluding, the Redemption Date on the principal balance of this Security to be redeemed.
“Treasury Rate” means, for any Redemption Date, the annual rate equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue equal to the Comparable Treasury Price, expressed as a percentage of its principal amount, for that Redemption Date. The yield of the Comparable Treasury Issue will be computed as of the second Business Day immediately preceding the date of the Redemption Notice.
“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent (defined below) that has a maturity comparable to the remaining maturity of this Security and that would be used in accordance with customary financial practice to price new issues of corporate debt securities with a maturity comparable to the remaining term of the Securities. The investment banks from which the Company will select a Quotation Agent are BofA Securities, Inc., Citigroup Global Markets Inc. and Morgan Stanley & Co. LLC, or their respective successors, or up to two other nationally recognized investment banking firms that are primary U.S. government securities dealers in New York City (each, a “Reference Treasury Dealer”). The Company will select one of the Reference Treasury Dealers to serve as its quotation agent (the “Quotation Agent”). If any of the firms referenced in the second

preceding sentence ceases to be a primary dealer of U.S. government securities in New York City, the Company shall appoint another nationally recognized investment banking firm that is a primary dealer as a substitute.
“Comparable Treasury Price” means, for any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations given to the Trustee by the Reference Treasury Dealers for that Redemption Date after excluding the highest and lowest of those Reference Treasury Dealer Quotations (or only one of the highest or lowest of the Reference Treasury Dealer Quotations if there are more than one), or (2) if the Trustee is given fewer than four Reference Treasury Dealer Quotations, the average of all those quotations.
“Reference Treasury Dealer Quotation” means, with respect to any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the Trustee by a Reference Treasury Dealer as of 3:30 p.m., New York time, on the second Business Day preceding the date of the Redemption Notice. The Trustee shall seek Reference Treasury Dealer Quotations in respect of any Redemption Date from each of the then-existing Reference Treasury Dealers.
“Remaining Scheduled Payments” means, with respect to the principal amount of each Security being redeemed, the remaining scheduled payments of principal and interest on that Security that would be due after the related Redemption Date but for the redemption. If, however, the Redemption Date is not an Interest Payment Date with respect to that Security, the amount of the next succeeding scheduled interest payment on that Security that would have been due will be deemed reduced by the amount of interest accrued on the Security to the Redemption Date.
On and after any Redemption Date, interest shall cease to accrue with respect to the Securities, or any portion of the Securities, called for redemption and for which the Redemption Price has been paid or made available for payment. On or prior to any Redemption Date, the Company shall deposit with the Paying Agent or the Trustee money sufficient to pay the Redemption Price on the Securities to be redeemed on such Redemption Date. If less than all of the Securities of this series are redeemed, the Trustee shall choose the Securities of this series to be redeemed by any method that it deems fair and appropriate, provided that if the Securities of this series are represented by one or more global Securities, interests in the Securities of this series will be selected for redemption by DTC in accordance with its standard procedures therefor.
Notwithstanding Section 1104 of the Indenture, the notice of any redemption referred to herein need not set forth the Redemption Price therefor but only the manner of calculation thereof. Promptly after the calculation of such Redemption Price, the Company shall give the Trustee notice thereof and the Trustee shall not be responsible for such calculation.
This Security is not repayable at the option of the Holder hereof and is not subject to the operation of any sinking fund.

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.
The provisions of Section 1402 and Section 1403 of the Indenture relating to defeasance and covenant defeasance, respectively, shall apply to this Security. Pursuant to Section 1404(5) and Section 1404(6) of the Indenture, any such defeasance or covenant defeasance shall be conditioned on receipt of an Opinion of Counsel relating to the federal income tax consequences of such defeasance or covenant defeasance.
The Company will not pay any Additional Amounts to Holders that are not U.S. persons (including any modification to the definition of such term) in respect of any tax, assessment or governmental charge.
The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of all Securities at the time Outstanding to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Outstanding Securities, to waive compliance by the Company with certain provisions of the Indenture, and contains provisions permitting the Holders of specified percentages in principal amount, in certain instances of the Outstanding Securities of individual series and in other instances of all Securities at the time Outstanding, to waive on behalf of all of the Holders of Securities of such individual series or of the Holders of all Securities at the time Outstanding, as the case may be, certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.
As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount, in certain instances of the Securities of this series at the time Outstanding and in other instances of all Outstanding Securities, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of not less than a majority in principal amount of Securities of this series at the time Outstanding or of all Outstanding Securities, as the case may be, a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for

the enforcement of any payment of principal hereof (and premium, if any) or interest hereon on or after the respective due dates expressed herein.
No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or make provision as provided in Article Fourteen of the Indenture for the payment of the amount of principal of (and premium, if any) and interest on this Security herein provided, and at the times, place and rate, and in the coin or currency, herein prescribed.
As provided in the Indenture and subject to certain limitations therein and herein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.
The Securities of this series are issuable only in registered form without coupons in minimum denominations of $1,000 and any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series of a different authorized denomination, as requested by the Holder surrendering the same.
No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.
Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.
All terms used in this Security that are defined in the Indenture shall have the meanings assigned to them in the Indenture.

Reference is hereby made to the further provisions of this Security set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place.
Unless the certificate of authentication hereon has been executed by the Trustee referred to on the reverse hereof by manual signature, this Security shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

TRUSTEE’S CERTIFICATE OF AUTHENTICATION
This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

Dated: _____________________

[REVERSE OF SECURITY]
This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Amended and Restated Indenture, dated as of May 1, 2001, as it may be supplemented from time to time (herein called the “Indenture”), between the Company (formerly known as United Technologies Corporation) and The Bank of New York Mellon Trust Company, N.A. (formerly The Bank of New York Trust Company, N.A.), as Trustee (successor to The Bank of New York) (herein called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the series of which this Security is a part), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof. The Indenture does not limit the aggregate principal amount of the Securities or the Securities of this series that may be issued thereunder. Additional Securities of this series may be issued from time to time hereafter; provided that any such additional Securities that are not fungible with this Security for U.S. federal income tax purposes will have a separate CUSIP, ISIN and other identifying number than this Security.
The Company may, at its option, redeem all or any part of this Security. If it chooses to do so, it shall mail or electronically deliver according to the procedures of DTC a notice of redemption (the “Redemption Notice”) to the Holder hereof (with a copy to the Trustee) not less than 15 days and not more than 60 days before the Redemption Date. The Redemption Price shall equal the greater of (i) 100% of the principal amount of this Security to be redeemed or (ii) the sum of the present values of the Remaining Scheduled Payments on the principal amount of this Security to be redeemed, discounted to the Redemption Date on a semiannual basis, assuming a 360-day year consisting of twelve 30-day months, at the Treasury Rate plus 20 basis points. The Redemption Price shall also include interest accrued to, but excluding, the Redemption Date on the principal balance of this Security to be redeemed.
“Treasury Rate” means, for any Redemption Date, the annual rate equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue equal to the Comparable Treasury Price, expressed as a percentage of its principal amount, for that Redemption Date. The yield of the Comparable Treasury Issue will be computed as of the second Business Day immediately preceding the date of the Redemption Notice.
“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent (defined below) that has a maturity comparable to the remaining maturity of this Security and that would be used in accordance with customary financial practice to price new issues of corporate debt securities with a maturity comparable to the remaining term of the Securities. The investment banks from which the Company will select a Quotation Agent are BofA Securities, Inc., Citigroup Global Markets Inc. and Morgan Stanley & Co. LLC, or their respective successors, or up to two other nationally recognized investment banking firms that are primary U.S. government securities dealers in New York City (each, a “Reference Treasury Dealer”). The Company will select one of the Reference Treasury Dealers to serve as its quotation agent (the “Quotation Agent”). If any of the firms referenced in the second

preceding sentence ceases to be a primary dealer of U.S. government securities in New York City, the Company shall appoint another nationally recognized investment banking firm that is a primary dealer as a substitute.
“Comparable Treasury Price” means, for any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations given to the Trustee by the Reference Treasury Dealers for that Redemption Date after excluding the highest and lowest of those Reference Treasury Dealer Quotations (or only one of the highest or lowest of the Reference Treasury Dealer Quotations if there are more than one), or (2) if the Trustee is given fewer than four Reference Treasury Dealer Quotations, the average of all those quotations.
“Reference Treasury Dealer Quotation” means, with respect to any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the Trustee by a Reference Treasury Dealer as of 3:30 p.m., New York time, on the second Business Day preceding the date of the Redemption Notice. The Trustee shall seek Reference Treasury Dealer Quotations in respect of any Redemption Date from each of the then-existing Reference Treasury Dealers.
“Remaining Scheduled Payments” means, with respect to the principal amount of each Security being redeemed, the remaining scheduled payments of principal and interest on that Security that would be due after the related Redemption Date but for the redemption. If, however, the Redemption Date is not an Interest Payment Date with respect to that Security, the amount of the next succeeding scheduled interest payment on that Security that would have been due will be deemed reduced by the amount of interest accrued on the Security to the Redemption Date.
On and after any Redemption Date, interest shall cease to accrue with respect to the Securities, or any portion of the Securities, called for redemption and for which the Redemption Price has been paid or made available for payment. On or prior to any Redemption Date, the Company shall deposit with the Paying Agent or the Trustee money sufficient to pay the Redemption Price on the Securities to be redeemed on such Redemption Date. If less than all of the Securities of this series are redeemed, the Trustee shall choose the Securities of this series to be redeemed by any method that it deems fair and appropriate, provided that if the Securities of this series are represented by one or more global Securities, interests in the Securities of this series will be selected for redemption by DTC in accordance with its standard procedures therefor.
Notwithstanding Section 1104 of the Indenture, the notice of any redemption referred to herein need not set forth the Redemption Price therefor but only the manner of calculation thereof. Promptly after the calculation of such Redemption Price, the Company shall give the Trustee notice thereof and the Trustee shall not be responsible for such calculation.
This Security is not repayable at the option of the Holder hereof and is not subject to the operation of any sinking fund.

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.
The provisions of Section 1402 and Section 1403 of the Indenture relating to defeasance and covenant defeasance, respectively, shall apply to this Security. Pursuant to Section 1404(5) and Section 1404(6) of the Indenture, any such defeasance or covenant defeasance shall be conditioned on receipt of an Opinion of Counsel relating to the federal income tax consequences of such defeasance or covenant defeasance.
The Company will not pay any Additional Amounts to Holders that are not U.S. persons (including any modification to the definition of such term) in respect of any tax, assessment or governmental charge.
The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of all Securities at the time Outstanding to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Outstanding Securities, to waive compliance by the Company with certain provisions of the Indenture, and contains provisions permitting the Holders of specified percentages in principal amount, in certain instances of the Outstanding Securities of individual series and in other instances of all Securities at the time Outstanding, to waive on behalf of all of the Holders of Securities of such individual series or of the Holders of all Securities at the time Outstanding, as the case may be, certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.
As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount, in certain instances of the Securities of this series at the time Outstanding and in other instances of all Outstanding Securities, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of not less than a majority in principal amount of Securities of this series at the time Outstanding or of all Outstanding Securities, as the case may be, a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for

the enforcement of any payment of principal hereof (and premium, if any) or interest hereon on or after the respective due dates expressed herein.
No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or make provision as provided in Article Fourteen of the Indenture for the payment of the amount of principal of (and premium, if any) and interest on this Security herein provided, and at the times, place and rate, and in the coin or currency, herein prescribed.
As provided in the Indenture and subject to certain limitations therein and herein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.
The Securities of this series are issuable only in registered form without coupons in minimum denominations of $2,000 and any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series of a different authorized denomination, as requested by the Holder surrendering the same.
No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.
Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

(formerly The Bank of New York Trust Company, N.A.), as Trustee (successor to The Bank of New York) (herein called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the series of which this Security is a part), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof.

Additional Securities of this series may be issued from time to time hereafter; provided that any such additional Securities that are not fungible with this Security for U.S. federal income tax purposes will have a separate CUSIP, ISIN and other identifying number than this Security.
The Company may, at its option, redeem all or any part of this Security. If it chooses to do so, it shall mail or electronically deliver according to the procedures of DTC a notice of redemption (the “Redemption Notice”) to the Holder hereof (with a copy to the Trustee) not less than 15 days and not more than 60 days before the Redemption Date. The Redemption Price shall equal the greater of (i) 100% of the principal amount of this Security to be redeemed or (ii) the sum of the present values of the Remaining Scheduled Payments on the principal amount of this Security to be redeemed, discounted to the Redemption Date on a semiannual basis, assuming a 360-day year consisting of twelve 30-day months, at the Treasury Rate plus 20 basis points. The Redemption Price shall also include interest accrued to, but excluding, the Redemption Date on the principal balance of this Security to be redeemed.
“Treasury Rate” means, for any Redemption Date, the annual rate equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue equal to the Comparable Treasury Price, expressed as a percentage of its principal amount, for that Redemption Date.

LLC, or their respective successors, or up to two other nationally recognized investment banking firms that are primary U.S. government securities dealers in New York City (each, a “Reference Treasury Dealer”). The Company will select one of the Reference Treasury Dealers to serve as its quotation agent (the “Quotation Agent”). If any of the firms referenced in the second

preceding sentence ceases to be a primary dealer of U.S. government securities in New York City, the Company shall appoint another nationally recognized investment banking firm that is a primary dealer as a substitute.
“Comparable Treasury Price” means, for any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations given to the Trustee by the Reference Treasury Dealers for that Redemption Date after excluding the highest and lowest of those Reference Treasury Dealer Quotations (or only one of the highest or lowest of the Reference Treasury Dealer Quotations if there are more than one), or (2) if the Trustee is given fewer than four Reference Treasury Dealer Quotations, the average of all those quotations.
“Reference Treasury Dealer Quotation” means, with respect to any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the Trustee by a Reference Treasury Dealer as of 3:30 p.m., New York time, on the second Business Day preceding the date of the Redemption Notice.

“Remaining Scheduled Payments” means, with respect to the principal amount of each Security being redeemed, the remaining scheduled payments of principal and interest on that Security that would be due after the related Redemption Date but for the redemption. If, however, the Redemption Date is not an Interest Payment Date with respect to that Security, the amount of the next succeeding scheduled interest payment on that Security that would have been due will be deemed reduced by the amount of interest accrued on the Security to the Redemption Date.
On and after any Redemption Date, interest shall cease to accrue with respect to the Securities, or any portion of the Securities, called for redemption and for which the Redemption Price has been paid or made available for payment. On or prior to any Redemption Date, the Company shall deposit with the Paying Agent or the Trustee money sufficient to pay the Redemption Price on the Securities to be redeemed on such Redemption Date. If less than all of the Securities of this series are redeemed, the Trustee shall choose the Securities of this series to be redeemed by any method that it deems fair and appropriate, provided that if the Securities of this series are represented by one or more global Securities, interests in the Securities of this series will be selected for redemption by DTC in accordance with its standard procedures therefor.
Notwithstanding Section 1104 of the Indenture, the notice of any redemption referred to herein need not set forth the Redemption Price therefor but only the manner of calculation thereof. Promptly after the calculation of such Redemption Price, the Company shall give the Trustee notice thereof and the Trustee shall not be responsible for such calculation.
This Security is not repayable at the option of the Holder hereof and is not subject to the operation of any sinking fund.

Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.
As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount, in certain instances of the Securities of this series at the time Outstanding and in other instances of all Outstanding Securities, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of not less than a majority in principal amount of Securities of this series at the time Outstanding or of all Outstanding Securities, as the case may be, a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity.

This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

| By: |

Dated: _____________________

[REVERSE OF SECURITY]
This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Amended and Restated Indenture, dated as of May 1, 2001, as it may be supplemented from time to time (herein called the “Indenture”), between the Company (formerly known as United Technologies Corporation) and The Bank of New York Mellon Trust Company, N.A. (formerly The Bank of New York Trust Company, N.A.), as Trustee (successor to The Bank of New York) (herein called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the series of which this Security is a part), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof. The Indenture does not limit the aggregate principal amount of the Securities or the Securities of this series that may be issued thereunder. Additional Securities of this series may be issued from time to time hereafter; provided that any such additional Securities that are not fungible with this Security for U.S. federal income tax purposes will have a separate CUSIP, ISIN and other identifying number than this Security.
The Company may, at its option, redeem all or any part of this Security. If it chooses to do so, it shall mail or electronically deliver according to the procedures of DTC a notice of redemption (the “Redemption Notice”) to the Holder hereof (with a copy to the Trustee) not less than 15 days and not more than 60 days before the Redemption Date. The Redemption Price shall equal the greater of (i) 100% of the principal amount of this Security to be redeemed or (ii) the sum of the present values of the Remaining Scheduled Payments on the principal amount of this Security to be redeemed, discounted to the Redemption Date on a semiannual basis, assuming a 360-day year consisting of twelve 30-day months, at the Treasury Rate plus 30 basis points. The Redemption Price shall also include interest accrued to, but excluding, the Redemption Date on the principal balance of this Security to be redeemed.
“Treasury Rate” means, for any Redemption Date, the annual rate equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue equal to the Comparable Treasury Price, expressed as a percentage of its principal amount, for that Redemption Date. The yield of the Comparable Treasury Issue will be computed as of the second Business Day immediately preceding the date of the Redemption Notice.
“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent (defined below) that has a maturity comparable to the remaining maturity of this Security and that would be used in accordance with customary financial practice to price new issues of corporate debt securities with a maturity comparable to the remaining term of the Securities. The investment banks from which the Company will select a Quotation Agent are BofA Securities, Inc., Citigroup Global Markets Inc. and Morgan Stanley & Co. LLC, or their respective successors, or up to two other nationally recognized investment banking firms that are primary U.S. government securities dealers in New York City (each, a “Reference Treasury Dealer”). The Company will select one of the Reference Treasury Dealers to serve as its quotation agent (the “Quotation Agent”). If any of the firms referenced in the second

preceding sentence ceases to be a primary dealer of U.S. government securities in New York City, the Company shall appoint another nationally recognized investment banking firm that is a primary dealer as a substitute.
“Comparable Treasury Price” means, for any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations given to the Trustee by the Reference Treasury Dealers for that Redemption Date after excluding the highest and lowest of those Reference Treasury Dealer Quotations (or only one of the highest or lowest of the Reference Treasury Dealer Quotations if there are more than one), or (2) if the Trustee is given fewer than four Reference Treasury Dealer Quotations, the average of all those quotations.
“Reference Treasury Dealer Quotation” means, with respect to any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the Trustee by a Reference Treasury Dealer as of 3:30 p.m., New York time, on the second Business Day preceding the date of the Redemption Notice. The Trustee shall seek Reference Treasury Dealer Quotations in respect of any Redemption Date from each of the then-existing Reference Treasury Dealers.
“Remaining Scheduled Payments” means, with respect to the principal amount of each Security being redeemed, the remaining scheduled payments of principal and interest on that Security that would be due after the related Redemption Date but for the redemption. If, however, the Redemption Date is not an Interest Payment Date with respect to that Security, the amount of the next succeeding scheduled interest payment on that Security that would have been due will be deemed reduced by the amount of interest accrued on the Security to the Redemption Date.
On and after any Redemption Date, interest shall cease to accrue with respect to the Securities, or any portion of the Securities, called for redemption and for which the Redemption Price has been paid or made available for payment. On or prior to any Redemption Date, the Company shall deposit with the Paying Agent or the Trustee money sufficient to pay the Redemption Price on the Securities to be redeemed on such Redemption Date. If less than all of the Securities of this series are redeemed, the Trustee shall choose the Securities of this series to be redeemed by any method that it deems fair and appropriate, provided that if the Securities of this series are represented by one or more global Securities, interests in the Securities of this series will be selected for redemption by DTC in accordance with its standard procedures therefor.
Notwithstanding Section 1104 of the Indenture, the notice of any redemption referred to herein need not set forth the Redemption Price therefor but only the manner of calculation thereof. Promptly after the calculation of such Redemption Price, the Company shall give the Trustee notice thereof and the Trustee shall not be responsible for such calculation.
This Security is not repayable at the option of the Holder hereof and is not subject to the operation of any sinking fund.

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.
The provisions of Section 1402 and Section 1403 of the Indenture relating to defeasance and covenant defeasance, respectively, shall apply to this Security. Pursuant to Section 1404(5) and Section 1404(6) of the Indenture, any such defeasance or covenant defeasance shall be conditioned on receipt of an Opinion of Counsel relating to the federal income tax consequences of such defeasance or covenant defeasance.
The Company will not pay any Additional Amounts to Holders that are not U.S. persons (including any modification to the definition of such term) in respect of any tax, assessment or governmental charge.
The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of all Securities at the time Outstanding to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Outstanding Securities, to waive compliance by the Company with certain provisions of the Indenture, and contains provisions permitting the Holders of specified percentages in principal amount, in certain instances of the Outstanding Securities of individual series and in other instances of all Securities at the time Outstanding, to waive on behalf of all of the Holders of Securities of such individual series or of the Holders of all Securities at the time Outstanding, as the case may be, certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.
As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount, in certain instances of the Securities of this series at the time Outstanding and in other instances of all Outstanding Securities, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of not less than a majority in principal amount of Securities of this series at the time Outstanding or of all Outstanding Securities, as the case may be, a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for

the enforcement of any payment of principal hereof (and premium, if any) or interest hereon on or after the respective due dates expressed herein.
No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or make provision as provided in Article Fourteen of the Indenture for the payment of the amount of principal of (and premium, if any) and interest on this Security herein provided, and at the times, place and rate, and in the coin or currency, herein prescribed.
As provided in the Indenture and subject to certain limitations therein and herein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.
The Securities of this series are issuable only in registered form without coupons in minimum denominations of $2,000 and any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series of a different authorized denomination, as requested by the Holder surrendering the same.
No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.
Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.
All terms used in this Security that are defined in the Indenture shall have the meanings assigned to them in the Indenture.

registered assigns, the principal sum of TWENTY-FOUR MILLION, FIVE HUNDRED AND SEVENTEEN THOUSAND DOLLARS ($24,517,000) on December 15, 2041 and to pay interest thereon (computed on the basis of a 360-day year comprised of twelve 30-day months) from December 15, 2019 or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semiannually in arrears on June 15 and December 15 of each year, and on the maturity date, commencing on June 15, 2020, at the rate of 4.700% per annum, until the principal hereof is paid or made available for payment.

TRUSTEE’S CERTIFICATE OF AUTHENTICATION
This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

| THE BANK OF NEW YORK MELLON TRUST COMPANY, N.A., as Trustee
| By: |

|  |  |  | Authorized Signatory
Dated: |  |  |  |

[REVERSE OF SECURITY]
This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Amended and Restated Indenture, dated as of May 1, 2001, as it may be supplemented from time to time (herein called the “Indenture”), between the Company (formerly known as United Technologies Corporation) and The Bank of New York Mellon Trust Company, N.A. (formerly The Bank of New York Trust Company, N.A.), as Trustee (successor to The Bank of New York) (herein called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the series of which this Security is a part), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof. The Indenture does not limit the aggregate principal amount of the Securities or the Securities of this series that may be issued thereunder. Additional Securities of this series may be issued from time to time hereafter; provided that any such additional Securities that are not fungible with this Security for U.S. federal income tax purposes will have a separate CUSIP, ISIN and other identifying number than this Security.
The Company may, at its option, redeem all or any part of this Security. If it chooses to do so, it shall mail or electronically deliver according to the procedures of DTC a notice of redemption (the “Redemption Notice”) to the Holder hereof (with a copy to the Trustee) not less than 15 days and not more than 60 days before the Redemption Date. The Redemption Price shall equal the greater of (i) 100% of the principal amount of this Security to be redeemed or (ii) the sum of the present values of the Remaining Scheduled Payments on the principal amount of this Security to be redeemed, discounted to the Redemption Date on a semiannual basis, assuming a 360-day year consisting of twelve 30-day months, at the Treasury Rate plus 30 basis points. The Redemption Price shall also include interest accrued to, but excluding, the Redemption Date on the principal balance of this Security to be redeemed.
“Treasury Rate” means, for any Redemption Date, the annual rate equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue equal to the Comparable Treasury Price, expressed as a percentage of its principal amount, for that Redemption Date. The yield of the Comparable Treasury Issue will be computed as of the second Business Day immediately preceding the date of the Redemption Notice.
“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent (defined below) that has a maturity comparable to the remaining maturity of this Security and that would be used in accordance with customary financial practice to price new issues of corporate debt securities with a maturity comparable to the remaining term of the Securities. The investment banks from which the Company will select a Quotation Agent are BofA Securities, Inc., Citigroup Global Markets Inc. and Morgan Stanley & Co. LLC, or their respective successors, or up to two other nationally recognized investment banking firms that are primary U.S. government securities dealers in New York City (each, a “Reference Treasury Dealer”). The Company will select one of the Reference Treasury Dealers to serve as its quotation agent (the “Quotation Agent”). If any of the firms referenced in the second

preceding sentence ceases to be a primary dealer of U.S. government securities in New York City, the Company shall appoint another nationally recognized investment banking firm that is a primary dealer as a substitute.
“Comparable Treasury Price” means, for any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations given to the Trustee by the Reference Treasury Dealers for that Redemption Date after excluding the highest and lowest of those Reference Treasury Dealer Quotations (or only one of the highest or lowest of the Reference Treasury Dealer Quotations if there are more than one), or (2) if the Trustee is given fewer than four Reference Treasury Dealer Quotations, the average of all those quotations.
“Reference Treasury Dealer Quotation” means, with respect to any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the Trustee by a Reference Treasury Dealer as of 3:30 p.m., New York time, on the second Business Day preceding the date of the Redemption Notice. The Trustee shall seek Reference Treasury Dealer Quotations in respect of any Redemption Date from each of the then-existing Reference Treasury Dealers.
“Remaining Scheduled Payments” means, with respect to the principal amount of each Security being redeemed, the remaining scheduled payments of principal and interest on that Security that would be due after the related Redemption Date but for the redemption. If, however, the Redemption Date is not an Interest Payment Date with respect to that Security, the amount of the next succeeding scheduled interest payment on that Security that would have been due will be deemed reduced by the amount of interest accrued on the Security to the Redemption Date.
On and after any Redemption Date, interest shall cease to accrue with respect to the Securities, or any portion of the Securities, called for redemption and for which the Redemption Price has been paid or made available for payment. On or prior to any Redemption Date, the Company shall deposit with the Paying Agent or the Trustee money sufficient to pay the Redemption Price on the Securities to be redeemed on such Redemption Date. If less than all of the Securities of this series are redeemed, the Trustee shall choose the Securities of this series to be redeemed by any method that it deems fair and appropriate, provided that if the Securities of this series are represented by one or more global Securities, interests in the Securities of this series will be selected for redemption by DTC in accordance with its standard procedures therefor.
Notwithstanding Section 1104 of the Indenture, the notice of any redemption referred to herein need not set forth the Redemption Price therefor but only the manner of calculation thereof. Promptly after the calculation of such Redemption Price, the Company shall give the Trustee notice thereof and the Trustee shall not be responsible for such calculation.
This Security is not repayable at the option of the Holder hereof and is not subject to the operation of any sinking fund.

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.
The provisions of Section 1402 and Section 1403 of the Indenture relating to defeasance and covenant defeasance, respectively, shall apply to this Security. Pursuant to Section 1404(5) and Section 1404(6) of the Indenture, any such defeasance or covenant defeasance shall be conditioned on receipt of an Opinion of Counsel relating to the federal income tax consequences of such defeasance or covenant defeasance.
The Company will not pay any Additional Amounts to Holders that are not U.S. persons (including any modification to the definition of such term) in respect of any tax, assessment or governmental charge.
The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of all Securities at the time Outstanding to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Outstanding Securities, to waive compliance by the Company with certain provisions of the Indenture, and contains provisions permitting the Holders of specified percentages in principal amount, in certain instances of the Outstanding Securities of individual series and in other instances of all Securities at the time Outstanding, to waive on behalf of all of the Holders of Securities of such individual series or of the Holders of all Securities at the time Outstanding, as the case may be, certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.
As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount, in certain instances of the Securities of this series at the time Outstanding and in other instances of all Outstanding Securities, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of not less than a majority in principal amount of Securities of this series at the time Outstanding or of all Outstanding Securities, as the case may be, a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for

the enforcement of any payment of principal hereof (and premium, if any) or interest hereon on or after the respective due dates expressed herein.
No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or make provision as provided in Article Fourteen of the Indenture for the payment of the amount of principal of (and premium, if any) and interest on this Security herein provided, and at the times, place and rate, and in the coin or currency, herein prescribed.
As provided in the Indenture and subject to certain limitations therein and herein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.
The Securities of this series are issuable only in registered form without coupons in minimum denominations of $2,000 and any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series of a different authorized denomination, as requested by the Holder surrendering the same.
No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.
Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

(formerly The Bank of New York Trust Company, N.A.), as Trustee (successor to The Bank of New York) (herein called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the series of which this Security is a part), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof. The Indenture does not limit the aggregate principal amount of the Securities or the Securities of this series that may be issued thereunder. Additional Securities of this series may be issued from time to time hereafter; provided that any such additional Securities that are not fungible with this Security for U.S. federal income tax purposes will have a separate CUSIP, ISIN and other identifying number than this Security.
The Company may, at its option, redeem all or any part of this Security. If it chooses to do so, it shall mail or electronically deliver according to the procedures of DTC a notice of redemption (the “Redemption Notice”) to the Holder hereof (with a copy to the Trustee) not less than 15 days and not more than 60 days before the Redemption Date. If this Security is redeemed prior to June 15, 2044, the Redemption Price shall equal the greater of (i) 100% of the principal amount of this Security to be redeemed or (ii) the sum of the present values of the Remaining Scheduled Payments on the principal amount of this Security to be redeemed, assuming for such purpose that this Security matured on June 15, 2044,discounted to the Redemption Date on a semiannual basis, assuming a 360-day year consisting of twelve 30-day months, at the Treasury Rate plus 20 basis points. If this Security is redeemed on or after June 15, 2044, the Redemption Price shall be 100% of the principal amount of this Security to be redeemed. In each case, the Redemption Price shall also include interest accrued to, but excluding, the Redemption Date on the principal balance of this Security to be redeemed.
“Treasury Rate” means, for any Redemption Date, the annual rate equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue equal to the Comparable Treasury Price, expressed as a percentage of its principal amount, for that Redemption Date. The yield of the Comparable Treasury Issue will be computed as of the second Business Day immediately preceding the date of the Redemption Notice.
“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent (defined below) that has a maturity comparable to the remaining maturity of this Security (assuming, for this purpose, that this Security matured on June 15, 2044) and that would be used in accordance with customary financial practice to price new issues of corporate debt securities with a maturity comparable to the remaining term of the Securities. The investment banks from which the Company will select a Quotation Agent are BofA Securities, Inc., Citigroup Global Markets Inc. and Morgan Stanley & Co. LLC, or their

respective successors, or up to two other nationally recognized investment banking firms that are primary U.S. government securities dealers in New York City (each, a “Reference Treasury Dealer”). The Company will select one of the Reference Treasury Dealers to serve as its quotation agent (the “Quotation Agent”). If any of the firms referenced in the second preceding sentence ceases to be a primary dealer of U.S. government securities in New York City, the Company shall appoint another nationally recognized investment banking firm that is a primary dealer as a substitute.
“Comparable Treasury Price” means, for any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations given to the Trustee by the Reference Treasury Dealers for that Redemption Date after excluding the highest and lowest of those Reference Treasury Dealer Quotations (or only one of the highest or lowest of the Reference Treasury Dealer Quotations if there are more than one), or (2) if the Trustee is given fewer than four Reference Treasury Dealer Quotations, the average of all those quotations.
“Reference Treasury Dealer Quotation” means, with respect to any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the Trustee by a Reference Treasury Dealer as of 3:30 p.m., New York time, on the second Business Day preceding the date of the Redemption Notice. The Trustee shall seek Reference Treasury Dealer Quotations in respect of any Redemption Date from each of the then-existing Reference Treasury Dealers.
“Remaining Scheduled Payments” means, with respect to the principal amount of each Security being redeemed, the remaining scheduled payments of principal and interest on that Security that would be due after the related Redemption Date but for the redemption, assuming for such purpose that this Security matured on June 15, 2044. If, however, the Redemption Date is not an Interest Payment Date with respect to that Security, the amount of the next succeeding scheduled interest payment on that Security that would have been due will be deemed reduced by the amount of interest accrued on the Security to the Redemption Date.
On and after any Redemption Date, interest shall cease to accrue with respect to the Securities, or any portion of the Securities, called for redemption and for which the Redemption Price has been paid or made available for payment. On or prior to any Redemption Date, the Company shall deposit with the Paying Agent or the Trustee money sufficient to pay the Redemption Price on the Securities to be redeemed on such Redemption Date. If less than all of the Securities of this series are redeemed, the Trustee shall choose the Securities of this series to be redeemed by any method that it deems fair and appropriate, provided that if the Securities of this series are represented by one or more global Securities, interests in the Securities of this series will be selected for redemption by DTC in accordance with its standard procedures therefor.
Notwithstanding Section 1104 of the Indenture, the notice of any redemption referred to herein need not set forth the Redemption Price therefor but only the manner of calculation thereof. Promptly after the calculation of such Redemption Price, the Company shall give the Trustee notice thereof and the Trustee shall not be responsible for such calculation.

This Security is not repayable at the option of the Holder hereof and is not subject to the operation of any sinking fund.
If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.
The provisions of Section 1402 and Section 1403 of the Indenture relating to defeasance and covenant defeasance, respectively, shall apply to this Security. Pursuant to Section 1404(5) and Section 1404(6) of the Indenture, any such defeasance or covenant defeasance shall be conditioned on receipt of an Opinion of Counsel relating to the federal income tax consequences of such defeasance or covenant defeasance.
The Company will not pay any Additional Amounts to Holders that are not U.S. persons (including any modification to the definition of such term) in respect of any tax, assessment or governmental charge.
The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of all Securities at the time Outstanding to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Outstanding Securities, to waive compliance by the Company with certain provisions of the Indenture, and contains provisions permitting the Holders of specified percentages in principal amount, in certain instances of the Outstanding Securities of individual series and in other instances of all Securities at the time Outstanding, to waive on behalf of all of the Holders of Securities of such individual series or of the Holders of all Securities at the time Outstanding, as the case may be, certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.
As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount, in certain instances of the Securities of this series at the time Outstanding and in other instances of all Outstanding Securities, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of not less than a majority in principal amount of Securities of this series at the time Outstanding or of all Outstanding Securities, as the case may be, a direction inconsistent with such request, and shall have failed to

institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof (and premium, if any) or interest hereon on or after the respective due dates expressed herein.
No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or make provision as provided in Article Fourteen of the Indenture for the payment of the amount of principal of (and premium, if any) and interest on this Security herein provided, and at the times, place and rate, and in the coin or currency, herein prescribed.
As provided in the Indenture and subject to certain limitations therein and herein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.
The Securities of this series are issuable only in registered form without coupons in minimum denominations of $2,000 and any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series of a different authorized denomination, as requested by the Holder surrendering the same.
No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.
Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

respective successors, or up to two other nationally recognized investment banking firms that are primary U.S. government securities dealers in New York City (each, a “Reference Treasury Dealer”).

On and after any Redemption Date, interest shall cease to accrue with respect to the Securities, or any portion of the Securities, called for redemption and for which the Redemption Price has been paid or made available for payment. On or prior to any Redemption Date, the Company shall deposit with the Paying Agent or the Trustee money sufficient to pay the Redemption Price on the Securities to be redeemed on such Redemption Date. If less than all of the Securities of this series are redeemed, the Trustee shall choose the Securities of this series to be redeemed by any method that it deems fair and appropriate, provided that if the Securities of this series are represented by one or more global Securities, interests in the Securities of this series will be selected for redemption by DTC in accordance with its standard procedures therefor.

RAYTHEON TECHNOLOGIES CORPORATION, a Delaware corporation (herein called the “Company”, which term includes any successor corporation under the Indenture hereinafter referred to), for value received, hereby promises to pay to CEDE & CO., or registered assigns, the principal sum of ONE HUNDRED SEVENTY MILLION, EIGHT HUNDRED AND SIXTY-FIVE THOUSAND DOLLARS ($170,865,000) on November 15, 2021 and to pay interest thereon (computed on the basis of a 360-day year comprised of twelve 30-day months) from May 15, 2020 or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semiannually in arrears on May 15 and November 15 of each year, and on the maturity date, commencing on November 15, 2020, at the rate of

3.100% per annum, until the principal hereof is paid or made available for payment. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the date that is fifteen calendar days prior to the scheduled Interest Payment Date, regardless of whether such date is a Business Day; provided that if this Security is held by a securities depositary in book-entry form, such date shall be the close of business on the Business Day immediately preceding the Interest Payment Date (the “Regular Record Date”); provided, that interest payable on the maturity date or any Redemption Date will be payable to the Person to whom the principal of this Security is payable. If the date on which a payment of interest or principal is scheduled to be paid is not a Business Day, then that interest or principal will be paid on the next succeeding Business Day, and no further interest will accrue as a result of such delay.

[REVERSE OF SECURITY]
This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Amended and Restated Indenture, dated as of May 1, 2001, as it may be supplemented from time to time (herein called the “Indenture”), between the Company (formerly known as United Technologies Corporation) and The Bank of New York Mellon Trust Company, N.A. (formerly The Bank of New York Trust Company, N.A.), as Trustee (successor to The Bank of New York) (herein called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the series of which this Security is a part), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof. The Indenture does not limit the aggregate principal amount of the Securities or the Securities of this series that may be issued thereunder. Additional Securities of this series may be issued from time to time hereafter; provided that any such additional Securities that are not fungible with this Security for U.S. federal income tax purposes will have a separate CUSIP, ISIN and other identifying number than this Security.
The Company may, at its option, redeem all or any part of this Security. If it chooses to do so, it shall mail or electronically deliver according to the procedures of DTC a notice of redemption (the “Redemption Notice”) to the Holder hereof (with a copy to the Trustee) not less than 15 days and not more than 60 days before the Redemption Date. If this Security is redeemed prior to August 15, 2021, the Redemption Price shall equal the greater of (i) 100% of the principal amount of this Security to be redeemed or (ii) the sum of the present values of the Remaining Scheduled Payments on the principal amount of this Security to be redeemed, assuming for such purpose that this Security matured on August 15, 2021, discounted to the Redemption Date on a semiannual basis, assuming a 360-day year consisting of twelve 30-day months, at the Treasury Rate plus 20 basis points. If this Security is redeemed on or after August 15, 2021, the Redemption Price shall be 100% of the principal amount of this Security to be redeemed. In each case, the Redemption Price shall also include interest accrued to, but excluding, the Redemption Date on the principal balance of this Security to be redeemed.
“Treasury Rate” means, for any Redemption Date, the annual rate equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue equal to the Comparable Treasury Price, expressed as a percentage of its principal amount, for that Redemption Date. The yield of the Comparable Treasury Issue will be computed as of the second Business Day immediately preceding the date of the Redemption Notice.
“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent (defined below) that has a maturity comparable to the remaining maturity of this Security (assuming, for this purpose, that this Security matured on August 15, 2021) and that would be used in accordance with customary financial practice to price new issues of corporate debt securities with a maturity comparable to the remaining term of the Securities. The investment banks from which the Company will select a Quotation Agent are BofA Securities, Inc., Citigroup Global Markets Inc. and Morgan Stanley & Co. LLC, or their

respective successors, or up to two other nationally recognized investment banking firms that are primary U.S. government securities dealers in New York City (each, a “Reference Treasury Dealer”). The Company will select one of the Reference Treasury Dealers to serve as its quotation agent (the “Quotation Agent”). If any of the firms referenced in the second preceding sentence ceases to be a primary dealer of U.S. government securities in New York City, the Company shall appoint another nationally recognized investment banking firm that is a primary dealer as a substitute.
“Comparable Treasury Price” means, for any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations given to the Trustee by the Reference Treasury Dealers for that Redemption Date after excluding the highest and lowest of those Reference Treasury Dealer Quotations (or only one of the highest or lowest of the Reference Treasury Dealer Quotations if there are more than one), or (2) if the Trustee is given fewer than four Reference Treasury Dealer Quotations, the average of all those quotations.
“Reference Treasury Dealer Quotation” means, with respect to any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the Trustee by a Reference Treasury Dealer as of 3:30 p.m., New York time, on the second Business Day preceding the date of the Redemption Notice. The Trustee shall seek Reference Treasury Dealer Quotations in respect of any Redemption Date from each of the then-existing Reference Treasury Dealers.
“Remaining Scheduled Payments” means, with respect to the principal amount of each Security being redeemed, the remaining scheduled payments of principal and interest on that Security that would be due after the related Redemption Date but for the redemption, assuming for such purpose that this Security matured on August 15, 2021. If, however, the Redemption Date is not an Interest Payment Date with respect to that Security, the amount of the next succeeding scheduled interest payment on that Security that would have been due will be deemed reduced by the amount of interest accrued on the Security to the Redemption Date.
On and after any Redemption Date, interest shall cease to accrue with respect to the Securities, or any portion of the Securities, called for redemption and for which the Redemption Price has been paid or made available for payment. On or prior to any Redemption Date, the Company shall deposit with the Paying Agent or the Trustee money sufficient to pay the Redemption Price on the Securities to be redeemed on such Redemption Date. If less than all of the Securities of this series are redeemed, the Trustee shall choose the Securities of this series to be redeemed by any method that it deems fair and appropriate, provided that if the Securities of this series are represented by one or more global Securities, interests in the Securities of this series will be selected for redemption by DTC in accordance with its standard procedures therefor.
Notwithstanding Section 1104 of the Indenture, the notice of any redemption referred to herein need not set forth the Redemption Price therefor but only the manner of calculation thereof. Promptly after the calculation of such Redemption Price, the Company shall give the Trustee notice thereof and the Trustee shall not be responsible for such calculation.

This Security is not repayable at the option of the Holder hereof and is not subject to the operation of any sinking fund.
If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.
The provisions of Section 1402 and Section 1403 of the Indenture relating to defeasance and covenant defeasance, respectively, shall apply to this Security. Pursuant to Section 1404(5) and Section 1404(6) of the Indenture, any such defeasance or covenant defeasance shall be conditioned on receipt of an Opinion of Counsel relating to the federal income tax consequences of such defeasance or covenant defeasance.
The Company will not pay any Additional Amounts to Holders that are not U.S. persons (including any modification to the definition of such term) in respect of any tax, assessment or governmental charge.
The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of all Securities at the time Outstanding to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Outstanding Securities, to waive compliance by the Company with certain provisions of the Indenture, and contains provisions permitting the Holders of specified percentages in principal amount, in certain instances of the Outstanding Securities of individual series and in other instances of all Securities at the time Outstanding, to waive on behalf of all of the Holders of Securities of such individual series or of the Holders of all Securities at the time Outstanding, as the case may be, certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.
As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount, in certain instances of the Securities of this series at the time Outstanding and in other instances of all Outstanding Securities, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of not less than a majority in principal amount of Securities of this series at the time Outstanding or of all Outstanding Securities, as the case may be, a direction inconsistent with such request, and shall have failed to

institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof (and premium, if any) or interest hereon on or after the respective due dates expressed herein.
No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or make provision as provided in Article Fourteen of the Indenture for the payment of the amount of principal of (and premium, if any) and interest on this Security herein provided, and at the times, place and rate, and in the coin or currency, herein prescribed.
As provided in the Indenture and subject to certain limitations therein and herein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.
The Securities of this series are issuable only in registered form without coupons in minimum denominations of $2,000 and any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series of a different authorized denomination, as requested by the Holder surrendering the same.
No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.
Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

registered assigns, the principal sum of TEN MILLION, TWO HUNDRED AND EIGHTY-FIVE THOUSAND DOLLARS ($10,285,000) on November 15, 2021 and to pay interest thereon (computed on the basis of a 360-day year comprised of twelve 30-day months) from May 15, 2020 or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semiannually in arrears on May 15 and November 15 of each year, and on the maturity date, commencing on November 15, 2020, at the rate of 3.100% per annum, until the principal hereof is paid or made available for payment.

TRUSTEE’S CERTIFICATE OF AUTHENTICATION
This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

| THE BANK OF NEW YORK MELLON TRUST COMPANY, N.A., as Trustee

| By: |

|  | Authorized Signatory

Dated: |  |

[REVERSE OF SECURITY]
This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Amended and Restated Indenture, dated as of May 1, 2001, as it may be supplemented from time to time (herein called the “Indenture”), between the Company (formerly known as United Technologies Corporation) and The Bank of New York Mellon Trust Company, N.A. (formerly The Bank of New York Trust Company, N.A.), as Trustee (successor to The Bank of New York) (herein called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the series of which this Security is a part), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof. The Indenture does not limit the aggregate principal amount of the Securities or the Securities of this series that may be issued thereunder. Additional Securities of this series may be issued from time to time hereafter; provided that any such additional Securities that are not fungible with this Security for U.S. federal income tax purposes will have a separate CUSIP, ISIN and other identifying number than this Security.
The Company may, at its option, redeem all or any part of this Security. If it chooses to do so, it shall mail or electronically deliver according to the procedures of DTC a notice of redemption (the “Redemption Notice”) to the Holder hereof (with a copy to the Trustee) not less than 15 days and not more than 60 days before the Redemption Date. If this Security is redeemed prior to August 15, 2021, the Redemption Price shall equal the greater of (i) 100% of the principal amount of this Security to be redeemed or (ii) the sum of the present values of the Remaining Scheduled Payments on the principal amount of this Security to be redeemed, assuming for such purpose that this Security matured on August 15, 2021, discounted to the Redemption Date on a semiannual basis, assuming a 360-day year consisting of twelve 30-day months, at the Treasury Rate plus 20 basis points. If this Security is redeemed on or after August 15, 2021, the Redemption Price shall be 100% of the principal amount of this Security to be redeemed. In each case, the Redemption Price shall also include interest accrued to, but excluding, the Redemption Date on the principal balance of this Security to be redeemed.
“Treasury Rate” means, for any Redemption Date, the annual rate equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue equal to the Comparable Treasury Price, expressed as a percentage of its principal amount, for that Redemption Date. The yield of the Comparable Treasury Issue will be computed as of the second Business Day immediately preceding the date of the Redemption Notice.
“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent (defined below) that has a maturity comparable to the remaining maturity of this Security (assuming, for this purpose, that this Security matured on August 15, 2021) and that would be used in accordance with customary financial practice to price new issues of corporate debt securities with a maturity comparable to the remaining term of the Securities. The investment banks from which the Company will select a Quotation Agent are BofA Securities, Inc., Citigroup Global Markets Inc. and Morgan Stanley & Co. LLC, or their

respective successors, or up to two other nationally recognized investment banking firms that are primary U.S. government securities dealers in New York City (each, a “Reference Treasury Dealer”). The Company will select one of the Reference Treasury Dealers to serve as its quotation agent (the “Quotation Agent”). If any of the firms referenced in the second preceding sentence ceases to be a primary dealer of U.S. government securities in New York City, the Company shall appoint another nationally recognized investment banking firm that is a primary dealer as a substitute.
“Comparable Treasury Price” means, for any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations given to the Trustee by the Reference Treasury Dealers for that Redemption Date after excluding the highest and lowest of those Reference Treasury Dealer Quotations (or only one of the highest or lowest of the Reference Treasury Dealer Quotations if there are more than one), or (2) if the Trustee is given fewer than four Reference Treasury Dealer Quotations, the average of all those quotations.
“Reference Treasury Dealer Quotation” means, with respect to any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the Trustee by a Reference Treasury Dealer as of 3:30 p.m., New York time, on the second Business Day preceding the date of the Redemption Notice. The Trustee shall seek Reference Treasury Dealer Quotations in respect of any Redemption Date from each of the then-existing Reference Treasury Dealers.
“Remaining Scheduled Payments” means, with respect to the principal amount of each Security being redeemed, the remaining scheduled payments of principal and interest on that Security that would be due after the related Redemption Date but for the redemption, assuming for such purpose that this Security matured on August 15, 2021. If, however, the Redemption Date is not an Interest Payment Date with respect to that Security, the amount of the next succeeding scheduled interest payment on that Security that would have been due will be deemed reduced by the amount of interest accrued on the Security to the Redemption Date.
On and after any Redemption Date, interest shall cease to accrue with respect to the Securities, or any portion of the Securities, called for redemption and for which the Redemption Price has been paid or made available for payment. On or prior to any Redemption Date, the Company shall deposit with the Paying Agent or the Trustee money sufficient to pay the Redemption Price on the Securities to be redeemed on such Redemption Date. If less than all of the Securities of this series are redeemed, the Trustee shall choose the Securities of this series to be redeemed by any method that it deems fair and appropriate, provided that if the Securities of this series are represented by one or more global Securities, interests in the Securities of this series will be selected for redemption by DTC in accordance with its standard procedures therefor.
Notwithstanding Section 1104 of the Indenture, the notice of any redemption referred to herein need not set forth the Redemption Price therefor but only the manner of calculation thereof. Promptly after the calculation of such Redemption Price, the Company shall give the Trustee notice thereof and the Trustee shall not be responsible for such calculation.

This Security is not repayable at the option of the Holder hereof and is not subject to the operation of any sinking fund.
If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.
The provisions of Section 1402 and Section 1403 of the Indenture relating to defeasance and covenant defeasance, respectively, shall apply to this Security. Pursuant to Section 1404(5) and Section 1404(6) of the Indenture, any such defeasance or covenant defeasance shall be conditioned on receipt of an Opinion of Counsel relating to the federal income tax consequences of such defeasance or covenant defeasance.
The Company will not pay any Additional Amounts to Holders that are not U.S. persons (including any modification to the definition of such term) in respect of any tax, assessment or governmental charge.
The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of all Securities at the time Outstanding to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Outstanding Securities, to waive compliance by the Company with certain provisions of the Indenture, and contains provisions permitting the Holders of specified percentages in principal amount, in certain instances of the Outstanding Securities of individual series and in other instances of all Securities at the time Outstanding, to waive on behalf of all of the Holders of Securities of such individual series or of the Holders of all Securities at the time Outstanding, as the case may be, certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.
As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount, in certain instances of the Securities of this series at the time Outstanding and in other instances of all Outstanding Securities, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of not less than a majority in principal amount of Securities of this series at the time Outstanding or of all Outstanding Securities, as the case may be, a direction inconsistent with such request, and shall have failed to

institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof (and premium, if any) or interest hereon on or after the respective due dates expressed herein.
No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or make provision as provided in Article Fourteen of the Indenture for the payment of the amount of principal of (and premium, if any) and interest on this Security herein provided, and at the times, place and rate, and in the coin or currency, herein prescribed.
As provided in the Indenture and subject to certain limitations therein and herein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.
The Securities of this series are issuable only in registered form without coupons in minimum denominations of $2,000 and any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series of a different authorized denomination, as requested by the Holder surrendering the same.
No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.
Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

The yield of the Comparable Treasury Issue will be computed as of the second Business Day immediately preceding the date of the Redemption Notice.
“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent (defined below) that has a maturity comparable to the remaining maturity of this Security (assuming, for this purpose, that this Security matured on February 15, 2022) and that would be used in accordance with customary financial practice to price new issues of corporate debt securities with a maturity comparable to the remaining term of the Securities. The investment banks from which the Company will select a Quotation Agent are BofA Securities, Inc., Citigroup Global Markets Inc. and Morgan Stanley & Co. LLC, or their respective successors, or up to two other nationally recognized investment banking firms that are primary U.S. government securities dealers in New York City (each, a “Reference Treasury Dealer”). The Company will select one of the Reference Treasury Dealers to serve as its quotation agent (the “Quotation Agent”). If any of the firms referenced in the second preceding sentence ceases to be a primary dealer of U.S. government securities in New York City, the Company shall appoint another nationally recognized investment banking firm that is a primary dealer as a substitute.

“Comparable Treasury Price” means, for any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations given to the Trustee by the Reference Treasury Dealers for that Redemption Date after excluding the highest and lowest of those Reference Treasury Dealer Quotations (or only one of the highest or lowest of the Reference Treasury Dealer Quotations if there are more than one), or (2) if the Trustee is given fewer than four Reference Treasury Dealer Quotations, the average of all those quotations.
“Reference Treasury Dealer Quotation” means, with respect to any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the Trustee by a Reference Treasury Dealer as of 3:30 p.m., New York time, on the second Business Day preceding the date of the Redemption Notice. The Trustee shall seek Reference Treasury Dealer Quotations in respect of any Redemption Date from each of the then-existing Reference Treasury Dealers.
“Remaining Scheduled Payments” means, with respect to the principal amount of each Security being redeemed, the remaining scheduled payments of principal and interest on that Security that would be due after the related Redemption Date but for the redemption, assuming for such purpose that this Security matured on February 15, 2022. If, however, the Redemption Date is not an Interest Payment Date with respect to that Security, the amount of the next succeeding scheduled interest payment on that Security that would have been due will be deemed reduced by the amount of interest accrued on the Security to the Redemption Date.
On and after any Redemption Date, interest shall cease to accrue with respect to the Securities, or any portion of the Securities, called for redemption and for which the Redemption Price has been paid or made available for payment. On or prior to any Redemption Date, the Company shall deposit with the Paying Agent or the Trustee money sufficient to pay the Redemption Price on the Securities to be redeemed on such Redemption Date. If less than all of the Securities of this series are redeemed, the Trustee shall choose the Securities of this series to be redeemed by any method that it deems fair and appropriate, provided that if the Securities of this series are represented by one or more global Securities, interests in the Securities of this series will be selected for redemption by DTC in accordance with its standard procedures therefor.
Notwithstanding Section 1104 of the Indenture, the notice of any redemption referred to herein need not set forth the Redemption Price therefor but only the manner of calculation thereof. Promptly after the calculation of such Redemption Price, the Company shall give the Trustee notice thereof and the Trustee shall not be responsible for such calculation.

This Security is not repayable at the option of the Holder hereof and is not subject to the operation of any sinking fund.
If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.
The provisions of Section 1402 and Section 1403 of the Indenture relating to defeasance and covenant defeasance, respectively, shall apply to this Security. Pursuant to Section 1404(5) and Section 1404(6) of the Indenture, any such defeasance or covenant defeasance shall be conditioned on receipt of an Opinion of Counsel relating to the federal income tax consequences of such defeasance or covenant defeasance.
The Company will not pay any Additional Amounts to Holders that are not U.S. persons (including any modification to the definition of such term) in respect of any tax, assessment or governmental charge.
The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of all Securities at the time Outstanding to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Outstanding Securities, to waive compliance by the Company with certain provisions of the Indenture, and contains provisions permitting the Holders of specified percentages in principal amount, in certain instances of the Outstanding Securities of individual series and in other instances of all Securities at the time Outstanding, to waive on behalf of all of the Holders of Securities of such individual series or of the Holders of all Securities at the time Outstanding, as the case may be, certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.
As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount, in certain instances of the Securities of this series at the time Outstanding and in other instances of all Outstanding Securities, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of not less than a majority in principal amount of Securities of this series at the time Outstanding or of all Outstanding Securities, as the case may be, a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof (and premium, if any) or interest hereon on or after the respective due dates expressed herein.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or make provision as provided in Article Fourteen of the Indenture for the payment of the amount of principal of (and premium, if any) and interest on this Security herein provided, and at the times, place and rate, and in the coin or currency, herein prescribed.
As provided in the Indenture and subject to certain limitations therein and herein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.
The Securities of this series are issuable only in registered form without coupons in minimum denominations of $2,000 and any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series of a different authorized denomination, as requested by the Holder surrendering the same.
No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.
Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

[REVERSE OF SECURITY]
This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Amended and Restated Indenture, dated as of May 1, 2001, as it may be supplemented from time to time (herein called the “Indenture”), between the Company (formerly known as United Technologies Corporation) and The Bank of New York Mellon Trust Company, N.A. (formerly The Bank of New York Trust Company, N.A.), as Trustee (successor to The Bank of New York) (herein called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the series of which this Security is a part), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof. The Indenture does not limit the aggregate principal amount of the Securities or the Securities of this series that may be issued thereunder. Additional Securities of this series may be issued from time to time hereafter; provided that any such additional Securities that are not fungible with this Security for U.S. federal income tax purposes will have a separate CUSIP, ISIN and other identifying number than this Security.
The Company may, at its option, redeem all or any part of this Security. If it chooses to do so, it shall mail or electronically deliver according to the procedures of DTC a notice of redemption (the “Redemption Notice”) to the Holder hereof (with a copy to the Trustee) not less than 15 days and not more than 60 days before the Redemption Date. If this Security is redeemed prior to February 15, 2022, the Redemption Price shall equal the greater of (i) 100% of the principal amount of this Security to be redeemed or (ii) the sum of the present values of the Remaining Scheduled Payments on the principal amount of this Security to be redeemed, assuming for such purpose that this Security matured on February 15, 2022, discounted to the Redemption Date on a semiannual basis, assuming a 360-day year consisting of twelve 30-day months, at the Treasury Rate plus 15 basis points. If this Security is redeemed on or after February 15, 2022, the Redemption Price shall be 100% of the principal amount of this Security to be redeemed. In each case, the Redemption Price shall also include interest accrued to, but excluding, the Redemption Date on the principal balance of this Security to be redeemed.
“Treasury Rate” means, for any Redemption Date, the annual rate equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue equal to the Comparable Treasury Price, expressed as a percentage of its principal amount, for that Redemption Date. The yield of the Comparable Treasury Issue will be computed as of the second Business Day immediately preceding the date of the Redemption Notice.
“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent (defined below) that has a maturity comparable to the remaining maturity of this Security (assuming, for this purpose, that this Security matured on February 15, 2022) and that would be used in accordance with customary financial practice to price new issues of corporate debt securities with a maturity comparable to the remaining term of the Securities. The investment banks from which the Company will select a Quotation Agent are BofA Securities, Inc., Citigroup Global Markets Inc. and Morgan Stanley & Co. LLC, or their

respective successors, or up to two other nationally recognized investment banking firms that are primary U.S. government securities dealers in New York City (each, a “Reference Treasury Dealer”). The Company will select one of the Reference Treasury Dealers to serve as its quotation agent (the “Quotation Agent”). If any of the firms referenced in the second preceding sentence ceases to be a primary dealer of U.S. government securities in New York City, the Company shall appoint another nationally recognized investment banking firm that is a primary dealer as a substitute.
“Comparable Treasury Price” means, for any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations given to the Trustee by the Reference Treasury Dealers for that Redemption Date after excluding the highest and lowest of those Reference Treasury Dealer Quotations (or only one of the highest or lowest of the Reference Treasury Dealer Quotations if there are more than one), or (2) if the Trustee is given fewer than four Reference Treasury Dealer Quotations, the average of all those quotations.
“Reference Treasury Dealer Quotation” means, with respect to any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the Trustee by a Reference Treasury Dealer as of 3:30 p.m., New York time, on the second Business Day preceding the date of the Redemption Notice. The Trustee shall seek Reference Treasury Dealer Quotations in respect of any Redemption Date from each of the then-existing Reference Treasury Dealers.
“Remaining Scheduled Payments” means, with respect to the principal amount of each Security being redeemed, the remaining scheduled payments of principal and interest on that Security that would be due after the related Redemption Date but for the redemption, assuming for such purpose that this Security matured on February 15, 2022. If, however, the Redemption Date is not an Interest Payment Date with respect to that Security, the amount of the next succeeding scheduled interest payment on that Security that would have been due will be deemed reduced by the amount of interest accrued on the Security to the Redemption Date.
On and after any Redemption Date, interest shall cease to accrue with respect to the Securities, or any portion of the Securities, called for redemption and for which the Redemption Price has been paid or made available for payment. On or prior to any Redemption Date, the Company shall deposit with the Paying Agent or the Trustee money sufficient to pay the Redemption Price on the Securities to be redeemed on such Redemption Date. If less than all of the Securities of this series are redeemed, the Trustee shall choose the Securities of this series to be redeemed by any method that it deems fair and appropriate, provided that if the Securities of this series are represented by one or more global Securities, interests in the Securities of this series will be selected for redemption by DTC in accordance with its standard procedures therefor.
Notwithstanding Section 1104 of the Indenture, the notice of any redemption referred to herein need not set forth the Redemption Price therefor but only the manner of calculation thereof. Promptly after the calculation of such Redemption Price, the Company shall give the Trustee notice thereof and the Trustee shall not be responsible for such calculation.

This Security is not repayable at the option of the Holder hereof and is not subject to the operation of any sinking fund.
If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.
The provisions of Section 1402 and Section 1403 of the Indenture relating to defeasance and covenant defeasance, respectively, shall apply to this Security. Pursuant to Section 1404(5) and Section 1404(6) of the Indenture, any such defeasance or covenant defeasance shall be conditioned on receipt of an Opinion of Counsel relating to the federal income tax consequences of such defeasance or covenant defeasance.
The Company will not pay any Additional Amounts to Holders that are not U.S. persons (including any modification to the definition of such term) in respect of any tax, assessment or governmental charge.
The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of all Securities at the time Outstanding to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Outstanding Securities, to waive compliance by the Company with certain provisions of the Indenture, and contains provisions permitting the Holders of specified percentages in principal amount, in certain instances of the Outstanding Securities of individual series and in other instances of all Securities at the time Outstanding, to waive on behalf of all of the Holders of Securities of such individual series or of the Holders of all Securities at the time Outstanding, as the case may be, certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.
As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount, in certain instances of the Securities of this series at the time Outstanding and in other instances of all Outstanding Securities, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of not less than a majority in principal amount of Securities of this series at the time Outstanding or of all Outstanding Securities, as the case may be, a direction inconsistent with such request, and shall have failed to

institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof (and premium, if any) or interest hereon on or after the respective due dates expressed herein.
No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or make provision as provided in Article Fourteen of the Indenture for the payment of the amount of principal of (and premium, if any) and interest on this Security herein provided, and at the times, place and rate, and in the coin or currency, herein prescribed.
As provided in the Indenture and subject to certain limitations therein and herein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.
The Securities of this series are issuable only in registered form without coupons in minimum denominations of $2,000 and any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series of a different authorized denomination, as requested by the Holder surrendering the same.
No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.
Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

[REVERSE OF SECURITY]
This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Amended and Restated Indenture, dated as of May 1, 2001, as it may be supplemented from time to time (herein called the “Indenture”), between the Company (formerly known as United Technologies Corporation) and The Bank of New York Mellon Trust Company, N.A. (formerly The Bank of New York Trust Company, N.A.), as Trustee (successor to The Bank of New York) (herein called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the series of which this Security is a part), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof. The Indenture does not limit the aggregate principal amount of the Securities or the Securities of this series that may be issued thereunder. Additional Securities of this series may be issued from time to time hereafter; provided that any such additional Securities that are not fungible with this Security for U.S. federal income tax purposes will have a separate CUSIP, ISIN and other identifying number than this Security.
The Company may, at its option, redeem all or any part of this Security. If it chooses to do so, it shall mail or electronically deliver according to the procedures of DTC a notice of redemption (the “Redemption Notice”) to the Holder hereof (with a copy to the Trustee) not less than 15 days and not more than 60 days before the Redemption Date. If this Security is redeemed prior to February 15, 2022, the Redemption Price shall equal the greater of (i) 100% of the principal amount of this Security to be redeemed or (ii) the sum of the present values of the Remaining Scheduled Payments on the principal amount of this Security to be redeemed, assuming for such purpose that this Security matured on February 15, 2022, discounted to the Redemption Date on a semiannual basis, assuming a 360-day year consisting of twelve 30-day months, at the Treasury Rate plus 15 basis points. If this Security is redeemed on or after February 15, 2022, the Redemption Price shall be 100% of the principal amount of this Security to be redeemed. In each case, the Redemption Price shall also include interest accrued to, but excluding, the Redemption Date on the principal balance of this Security to be redeemed.
“Treasury Rate” means, for any Redemption Date, the annual rate equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue equal to the Comparable Treasury Price, expressed as a percentage of its principal amount, for that Redemption Date. The yield of the Comparable Treasury Issue will be computed as of the second Business Day immediately preceding the date of the Redemption Notice.
“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent (defined below) that has a maturity comparable to the remaining maturity of this Security (assuming, for this purpose, that this Security matured on February 15, 2022) and that would be used in accordance with customary financial practice to price new issues of corporate debt securities with a maturity comparable to the remaining term of the Securities. The investment banks from which the Company will select a Quotation Agent are BofA Securities, Inc., Citigroup Global Markets Inc. and Morgan Stanley & Co. LLC, or their

respective successors, or up to two other nationally recognized investment banking firms that are primary U.S. government securities dealers in New York City (each, a “Reference Treasury Dealer”). The Company will select one of the Reference Treasury Dealers to serve as its quotation agent (the “Quotation Agent”). If any of the firms referenced in the second preceding sentence ceases to be a primary dealer of U.S. government securities in New York City, the Company shall appoint another nationally recognized investment banking firm that is a primary dealer as a substitute.
“Comparable Treasury Price” means, for any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations given to the Trustee by the Reference Treasury Dealers for that Redemption Date after excluding the highest and lowest of those Reference Treasury Dealer Quotations (or only one of the highest or lowest of the Reference Treasury Dealer Quotations if there are more than one), or (2) if the Trustee is given fewer than four Reference Treasury Dealer Quotations, the average of all those quotations.
“Reference Treasury Dealer Quotation” means, with respect to any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the Trustee by a Reference Treasury Dealer as of 3:30 p.m., New York time, on the second Business Day preceding the date of the Redemption Notice. The Trustee shall seek Reference Treasury Dealer Quotations in respect of any Redemption Date from each of the then-existing Reference Treasury Dealers.
“Remaining Scheduled Payments” means, with respect to the principal amount of each Security being redeemed, the remaining scheduled payments of principal and interest on that Security that would be due after the related Redemption Date but for the redemption, assuming for such purpose that this Security matured on February 15, 2022. If, however, the Redemption Date is not an Interest Payment Date with respect to that Security, the amount of the next succeeding scheduled interest payment on that Security that would have been due will be deemed reduced by the amount of interest accrued on the Security to the Redemption Date.
On and after any Redemption Date, interest shall cease to accrue with respect to the Securities, or any portion of the Securities, called for redemption and for which the Redemption Price has been paid or made available for payment. On or prior to any Redemption Date, the Company shall deposit with the Paying Agent or the Trustee money sufficient to pay the Redemption Price on the Securities to be redeemed on such Redemption Date. If less than all of the Securities of this series are redeemed, the Trustee shall choose the Securities of this series to be redeemed by any method that it deems fair and appropriate, provided that if the Securities of this series are represented by one or more global Securities, interests in the Securities of this series will be selected for redemption by DTC in accordance with its standard procedures therefor.
Notwithstanding Section 1104 of the Indenture, the notice of any redemption referred to herein need not set forth the Redemption Price therefor but only the manner of calculation thereof. Promptly after the calculation of such Redemption Price, the Company shall give the Trustee notice thereof and the Trustee shall not be responsible for such calculation.

This Security is not repayable at the option of the Holder hereof and is not subject to the operation of any sinking fund.
If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.
The provisions of Section 1402 and Section 1403 of the Indenture relating to defeasance and covenant defeasance, respectively, shall apply to this Security. Pursuant to Section 1404(5) and Section 1404(6) of the Indenture, any such defeasance or covenant defeasance shall be conditioned on receipt of an Opinion of Counsel relating to the federal income tax consequences of such defeasance or covenant defeasance.
The Company will not pay any Additional Amounts to Holders that are not U.S. persons (including any modification to the definition of such term) in respect of any tax, assessment or governmental charge.
The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of all Securities at the time Outstanding to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Outstanding Securities, to waive compliance by the Company with certain provisions of the Indenture, and contains provisions permitting the Holders of specified percentages in principal amount, in certain instances of the Outstanding Securities of individual series and in other instances of all Securities at the time Outstanding, to waive on behalf of all of the Holders of Securities of such individual series or of the Holders of all Securities at the time Outstanding, as the case may be, certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.
As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount, in certain instances of the Securities of this series at the time Outstanding and in other instances of all Outstanding Securities, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of not less than a majority in principal amount of Securities of this series at the time Outstanding or of all Outstanding Securities, as the case may be, a direction inconsistent with such request, and shall have failed to

institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof (and premium, if any) or interest hereon on or after the respective due dates expressed herein.
No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or make provision as provided in Article Fourteen of the Indenture for the payment of the amount of principal of (and premium, if any) and interest on this Security herein provided, and at the times, place and rate, and in the coin or currency, herein prescribed.
As provided in the Indenture and subject to certain limitations therein and herein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.
The Securities of this series are issuable only in registered form without coupons in minimum denominations of $2,000 and any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series of a different authorized denomination, as requested by the Holder surrendering the same.
No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.
Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.
All terms used in this Security that are defined in the Indenture shall have the meanings assigned to them in the Indenture.

| TRUST COMPANY, N.A., as Trustee
| By: |
|  | Authorized Signatory
Dated: |  |  |  |

[REVERSE OF SECURITY]
This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Amended and Restated Indenture, dated as of May 1, 2001, as it may be supplemented from time to time (herein called the “Indenture”), between the Company (formerly known as United Technologies Corporation) and The Bank of New York Mellon Trust Company, N.A. (formerly The Bank of New York Trust Company, N.A.), as Trustee (successor to The Bank of New York) (herein called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the series of which this Security is a part), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof. The Indenture does not limit the aggregate principal amount of the Securities or the Securities of this series that may be issued thereunder. Additional Securities of this series may be issued from time to time hereafter; provided that any such additional Securities that are not fungible with this Security for U.S. federal income tax purposes will have a separate CUSIP, ISIN and other identifying number than this Security.
The Company may, at its option, redeem all or any part of this Security. If it chooses to do so, it shall mail or electronically deliver according to the procedures of DTC a notice of redemption (the “Redemption Notice”) to the Holder hereof (with a copy to the Trustee) not less than 15 days and not more than 60 days before the Redemption Date. If this Security is redeemed prior to September 15, 2023, the Redemption Price shall equal the greater of (i) 100% of the principal amount of this Security to be redeemed or (ii) the sum of the present values of the Remaining Scheduled Payments on the principal amount of this Security to be redeemed, assuming for such purpose that this Security matured on September 15, 2023, discounted to the Redemption Date on a semiannual basis, assuming a 360-day year consisting of twelve 30-day months, at the Treasury Rate plus 15 basis points. If this Security is redeemed on or after September 15, 2023, the Redemption Price shall be 100% of the principal amount of this Security to be redeemed. In each case, the Redemption Price shall also include interest accrued to, but excluding, the Redemption Date on the principal balance of this Security to be redeemed.
“Treasury Rate” means, for any Redemption Date, the annual rate equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue equal to the Comparable Treasury Price, expressed as a percentage of its principal amount, for that Redemption Date. The yield of the Comparable Treasury Issue will be computed as of the second Business Day immediately preceding the date of the Redemption Notice.
“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent (defined below) that has a maturity comparable to the remaining maturity of this Security (assuming, for this purpose, that this Security matured on September 15, 2023) and that would be used in accordance with customary financial practice to price new issues of corporate debt securities with a maturity comparable to the remaining term of the Securities. The investment banks from which the Company will select a Quotation Agent are BofA Securities, Inc., Citigroup Global Markets Inc. and Morgan Stanley & Co. LLC, or their

respective successors, or up to two other nationally recognized investment banking firms that are primary U.S. government securities dealers in New York City (each, a “Reference Treasury Dealer”). The Company will select one of the Reference Treasury Dealers to serve as its quotation agent (the “Quotation Agent”). If any of the firms referenced in the second preceding sentence ceases to be a primary dealer of U.S. government securities in New York City, the Company shall appoint another nationally recognized investment banking firm that is a primary dealer as a substitute.
“Comparable Treasury Price” means, for any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations given to the Trustee by the Reference Treasury Dealers for that Redemption Date after excluding the highest and lowest of those Reference Treasury Dealer Quotations (or only one of the highest or lowest of the Reference Treasury Dealer Quotations if there are more than one), or (2) if the Trustee is given fewer than four Reference Treasury Dealer Quotations, the average of all those quotations.
“Reference Treasury Dealer Quotation” means, with respect to any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the Trustee by a Reference Treasury Dealer as of 3:30 p.m., New York time, on the second Business Day preceding the date of the Redemption Notice. The Trustee shall seek Reference Treasury Dealer Quotations in respect of any Redemption Date from each of the then-existing Reference Treasury Dealers.
“Remaining Scheduled Payments” means, with respect to the principal amount of each Security being redeemed, the remaining scheduled payments of principal and interest on that Security that would be due after the related Redemption Date but for the redemption, assuming for such purpose that this Security matured on September 15, 2023. If, however, the Redemption Date is not an Interest Payment Date with respect to that Security, the amount of the next succeeding scheduled interest payment on that Security that would have been due will be deemed reduced by the amount of interest accrued on the Security to the Redemption Date.
On and after any Redemption Date, interest shall cease to accrue with respect to the Securities, or any portion of the Securities, called for redemption and for which the Redemption Price has been paid or made available for payment. On or prior to any Redemption Date, the Company shall deposit with the Paying Agent or the Trustee money sufficient to pay the Redemption Price on the Securities to be redeemed on such Redemption Date. If less than all of the Securities of this series are redeemed, the Trustee shall choose the Securities of this series to be redeemed by any method that it deems fair and appropriate, provided that if the Securities of this series are represented by one or more global Securities, interests in the Securities of this series will be selected for redemption by DTC in accordance with its standard procedures therefor.
Notwithstanding Section 1104 of the Indenture, the notice of any redemption referred to herein need not set forth the Redemption Price therefor but only the manner of calculation thereof. Promptly after the calculation of such Redemption Price, the Company shall give the Trustee notice thereof and the Trustee shall not be responsible for such calculation.

This Security is not repayable at the option of the Holder hereof and is not subject to the operation of any sinking fund.
If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.
The provisions of Section 1402 and Section 1403 of the Indenture relating to defeasance and covenant defeasance, respectively, shall apply to this Security. Pursuant to Section 1404(5) and Section 1404(6) of the Indenture, any such defeasance or covenant defeasance shall be conditioned on receipt of an Opinion of Counsel relating to the federal income tax consequences of such defeasance or covenant defeasance.
The Company will not pay any Additional Amounts to Holders that are not U.S. persons (including any modification to the definition of such term) in respect of any tax, assessment or governmental charge.
The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of all Securities at the time Outstanding to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Outstanding Securities, to waive compliance by the Company with certain provisions of the Indenture, and contains provisions permitting the Holders of specified percentages in principal amount, in certain instances of the Outstanding Securities of individual series and in other instances of all Securities at the time Outstanding, to waive on behalf of all of the Holders of Securities of such individual series or of the Holders of all Securities at the time Outstanding, as the case may be, certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.
As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount, in certain instances of the Securities of this series at the time Outstanding and in other instances of all Outstanding Securities, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of not less than a majority in principal amount of Securities of this series at the time Outstanding or of all Outstanding Securities, as the case may be, a direction inconsistent with such request, and shall have failed to

institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof (and premium, if any) or interest hereon on or after the respective due dates expressed herein.
No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or make provision as provided in Article Fourteen of the Indenture for the payment of the amount of principal of (and premium, if any) and interest on this Security herein provided, and at the times, place and rate, and in the coin or currency, herein prescribed.
As provided in the Indenture and subject to certain limitations therein and herein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.
The Securities of this series are issuable only in registered form without coupons in minimum denominations of $2,000 and any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series of a different authorized denomination, as requested by the Holder surrendering the same.
No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.
Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

“Remaining Scheduled Payments” means, with respect to the principal amount of each Security being redeemed, the remaining scheduled payments of principal and interest on that Security that would be due after the related Redemption Date but for the redemption, assuming for such purpose that this Security matured on September 15, 2023. If, however, the Redemption Date is not an Interest Payment Date with respect to that Security, the amount of the next succeeding scheduled interest payment on that Security that would have been due will be deemed reduced by the amount of interest accrued on the Security to the Redemption Date.
On and after any Redemption Date, interest shall cease to accrue with respect to the Securities, or any portion of the Securities, called for redemption and for which the Redemption Price has been paid or made available for payment. On or prior to any Redemption Date, the Company shall deposit with the Paying Agent or the Trustee money sufficient to pay the Redemption Price on the Securities to be redeemed on such Redemption Date. If less than all of the Securities of this series are redeemed, the Trustee shall choose the Securities of this series to be redeemed by any method that it deems fair and appropriate, provided that if the Securities of this series are represented by one or more global Securities, interests in the Securities of this series will be selected for redemption by DTC in accordance with its standard procedures therefor.
Notwithstanding Section 1104 of the Indenture, the notice of any redemption referred to herein need not set forth the Redemption Price therefor but only the manner of calculation thereof. Promptly after the calculation of such Redemption Price, the Company shall give the Trustee notice thereof and the Trustee shall not be responsible for such calculation.

This Security is not repayable at the option of the Holder hereof and is not subject to the operation of any sinking fund.
If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.
The provisions of Section 1402 and Section 1403 of the Indenture relating to defeasance and covenant defeasance, respectively, shall apply to this Security. Pursuant to Section 1404(5) and Section 1404(6) of the Indenture, any such defeasance or covenant defeasance shall be conditioned on receipt of an Opinion of Counsel relating to the federal income tax consequences of such defeasance or covenant defeasance.
The Company will not pay any Additional Amounts to Holders that are not U.S. persons (including any modification to the definition of such term) in respect of any tax, assessment or governmental charge.
The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of all Securities at the time Outstanding to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Outstanding Securities, to waive compliance by the Company with certain provisions of the Indenture, and contains provisions permitting the Holders of specified percentages in principal amount, in certain instances of the Outstanding Securities of individual series and in other instances of all Securities at the time Outstanding, to waive on behalf of all of the Holders of Securities of such individual series or of the Holders of all Securities at the time Outstanding, as the case may be, certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.
As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount, in certain instances of the Securities of this series at the time Outstanding and in other instances of all Outstanding Securities, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of not less than a majority in principal amount of Securities of this series at the time Outstanding or of all Outstanding Securities, as the case may be, a direction inconsistent with such request, and shall have failed to

institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof (and premium, if any) or interest hereon on or after the respective due dates expressed herein.
No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or make provision as provided in Article Fourteen of the Indenture for the payment of the amount of principal of (and premium, if any) and interest on this Security herein provided, and at the times, place and rate, and in the coin or currency, herein prescribed.

This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

| By: |
|  | Authorized Signatory

Dated: _____________________

[REVERSE OF SECURITY]
This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Amended and Restated Indenture, dated as of May 1, 2001, as it may be supplemented from time to time (herein called the “Indenture”), between the Company (formerly known as United Technologies Corporation) and The Bank of New York Mellon Trust Company, N.A. (formerly The Bank of New York Trust Company, N.A.), as Trustee (successor to The Bank of New York) (herein called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the series of which this Security is a part), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof. The Indenture does not limit the aggregate principal amount of the Securities or the Securities of this series that may be issued thereunder. Additional Securities of this series may be issued from time to time hereafter; provided that any such additional Securities that are not fungible with this Security for U.S. federal income tax purposes will have a separate CUSIP, ISIN and other identifying number than this Security.
The Company may, at its option, redeem all or any part of this Security. If it chooses to do so, it shall mail or electronically deliver according to the procedures of DTC a notice of redemption (the “Redemption Notice”) to the Holder hereof (with a copy to the Trustee) not less than 15 days and not more than 60 days before the Redemption Date. If this Security is redeemed prior to January 15, 2024, the Redemption Price shall equal the greater of (i) 100% of the principal amount of this Security to be redeemed or (ii) the sum of the present values of the Remaining Scheduled Payments on the principal amount of this Security to be redeemed, assuming for such purpose that this Security matured on January 15, 2024, discounted to the Redemption Date on a semiannual basis, assuming a 360-day year consisting of twelve 30-day months, at the Treasury Rate plus 15 basis points. If this Security is redeemed on or after January 15, 2024, the Redemption Price shall be 100% of the principal amount of this Security to be redeemed. In each case, the Redemption Price shall also include interest accrued to, but excluding, the Redemption Date on the principal balance of this Security to be redeemed.
“Treasury Rate” means, for any Redemption Date, the annual rate equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue equal to the Comparable Treasury Price, expressed as a percentage of its principal amount, for that Redemption Date. The yield of the Comparable Treasury Issue will be computed as of the second Business Day immediately preceding the date of the Redemption Notice.
“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent (defined below) that has a maturity comparable to the remaining maturity of this Security (assuming, for this purpose, that this Security matured on January 15, 2024) and that would be used in accordance with customary financial practice to price new issues of corporate debt securities with a maturity comparable to the remaining term of the Securities. The investment banks from which the Company will select a Quotation Agent are BofA Securities, Inc., Citigroup Global Markets Inc. and Morgan Stanley & Co. LLC, or their respective successors, or up to two other nationally recognized investment banking firms that are primary U.S. government securities dealers in New York City (each, a “Reference Treasury Dealer”). The Company will select one of the Reference Treasury Dealers to serve as its quotation agent (the “Quotation Agent”). If any of the firms referenced in the second preceding sentence ceases to be a primary dealer of U.S. government securities in New York City, the Company shall appoint another nationally recognized investment banking firm that is a primary dealer as a substitute.

“Comparable Treasury Price” means, for any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations given to the Trustee by the Reference Treasury Dealers for that Redemption Date after excluding the highest and lowest of those Reference Treasury Dealer Quotations (or only one of the highest or lowest of the Reference Treasury Dealer Quotations if there are more than one), or (2) if the Trustee is given fewer than four Reference Treasury Dealer Quotations, the average of all those quotations.
“Reference Treasury Dealer Quotation” means, with respect to any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the Trustee by a Reference Treasury Dealer as of 3:30 p.m., New York time, on the second Business Day preceding the date of the Redemption Notice. The Trustee shall seek Reference Treasury Dealer Quotations in respect of any Redemption Date from each of the then-existing Reference Treasury Dealers.
“Remaining Scheduled Payments” means, with respect to the principal amount of each Security being redeemed, the remaining scheduled payments of principal and interest on that Security that would be due after the related Redemption Date but for the redemption, assuming for such purpose that this Security matured on January 15, 2024. If, however, the Redemption Date is not an Interest Payment Date with respect to that Security, the amount of the next succeeding scheduled interest payment on that Security that would have been due will be deemed reduced by the amount of interest accrued on the Security to the Redemption Date.
On and after any Redemption Date, interest shall cease to accrue with respect to the Securities, or any portion of the Securities, called for redemption and for which the Redemption Price has been paid or made available for payment. On or prior to any Redemption Date, the Company shall deposit with the Paying Agent or the Trustee money sufficient to pay the Redemption Price on the Securities to be redeemed on such Redemption Date. If less than all of the Securities of this series are redeemed, the Trustee shall choose the Securities of this series to be redeemed by any method that it deems fair and appropriate, provided that if the Securities of this series are represented by one or more global Securities, interests in the Securities of this series will be selected for redemption by DTC in accordance with its standard procedures therefor.
Notwithstanding Section 1104 of the Indenture, the notice of any redemption referred to herein need not set forth the Redemption Price therefor but only the manner of calculation thereof. Promptly after the calculation of such Redemption Price, the Company shall give the Trustee notice thereof and the Trustee shall not be responsible for such calculation.

This Security is not repayable at the option of the Holder hereof and is not subject to the operation of any sinking fund.
If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.
The provisions of Section 1402 and Section 1403 of the Indenture relating to defeasance and covenant defeasance, respectively, shall apply to this Security. Pursuant to Section 1404(5) and Section 1404(6) of the Indenture, any such defeasance or covenant defeasance shall be conditioned on receipt of an Opinion of Counsel relating to the federal income tax consequences of such defeasance or covenant defeasance.
The Company will not pay any Additional Amounts to Holders that are not U.S. persons (including any modification to the definition of such term) in respect of any tax, assessment or governmental charge.
The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of all Securities at the time Outstanding to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Outstanding Securities, to waive compliance by the Company with certain provisions of the Indenture, and contains provisions permitting the Holders of specified percentages in principal amount, in certain instances of the Outstanding Securities of individual series and in other instances of all Securities at the time Outstanding, to waive on behalf of all of the Holders of Securities of such individual series or of the Holders of all Securities at the time Outstanding, as the case may be, certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.
As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount, in certain instances of the Securities of this series at the time Outstanding and in other instances of all Outstanding Securities, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of not less than a majority in principal amount of Securities of this series at the time Outstanding or of all Outstanding Securities, as the case may be, a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof (and premium, if any) or interest hereon on or after the respective due dates expressed herein.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or make provision as provided in Article Fourteen of the Indenture for the payment of the amount of principal of (and premium, if any) and interest on this Security herein provided, and at the times, place and rate, and in the coin or currency, herein prescribed.
As provided in the Indenture and subject to certain limitations therein and herein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.
The Securities of this series are issuable only in registered form without coupons in minimum denominations of $2,000 and any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series of a different authorized denomination, as requested by the Holder surrendering the same.
No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.
Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.
All terms used in this Security that are defined in the Indenture shall have the meanings assigned to them in the Indenture.

TRUSTEE’S CERTIFICATE OF AUTHENTICATION
This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

| THE BANK OF NEW YORK MELLON TRUST COMPANY, N.A., as Trustee
| By: |

|  | Authorized Signatory
Dated: |  |  |  |

[REVERSE OF SECURITY]
This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Amended and Restated Indenture, dated as of May 1, 2001, as it may be supplemented from time to time (herein called the “Indenture”), between the Company (formerly known as United Technologies Corporation) and The Bank of New York Mellon Trust Company, N.A. (formerly The Bank of New York Trust Company, N.A.), as Trustee (successor to The Bank of New York) (herein called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the series of which this Security is a part), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof. The Indenture does not limit the aggregate principal amount of the Securities or the Securities of this series that may be issued thereunder. Additional Securities of this series may be issued from time to time hereafter; provided that any such additional Securities that are not fungible with this Security for U.S. federal income tax purposes will have a separate CUSIP, ISIN and other identifying number than this Security.
The Company may, at its option, redeem all or any part of this Security. If it chooses to do so, it shall mail or electronically deliver according to the procedures of DTC a notice of redemption (the “Redemption Notice”) to the Holder hereof (with a copy to the Trustee) not less than 15 days and not more than 60 days before the Redemption Date. If this Security is redeemed prior to January 15, 2024, the Redemption Price shall equal the greater of (i) 100% of the principal amount of this Security to be redeemed or (ii) the sum of the present values of the Remaining Scheduled Payments on the principal amount of this Security to be redeemed, assuming for such purpose that this Security matured on January 15, 2024, discounted to the Redemption Date on a semiannual basis, assuming a 360-day year consisting of twelve 30-day months, at the Treasury Rate plus 15 basis points. If this Security is redeemed on or after January 15, 2024, the Redemption Price shall be 100% of the principal amount of this Security to be redeemed. In each case, the Redemption Price shall also include interest accrued to, but excluding, the Redemption Date on the principal balance of this Security to be redeemed.
“Treasury Rate” means, for any Redemption Date, the annual rate equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue equal to the Comparable Treasury Price, expressed as a percentage of its principal amount, for that Redemption Date. The yield of the Comparable Treasury Issue will be computed as of the second Business Day immediately preceding the date of the Redemption Notice.
“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent (defined below) that has a maturity comparable to the remaining maturity of this Security (assuming, for this purpose, that this Security matured on January 15, 2024) and that would be used in accordance with customary financial practice to price new issues of corporate debt securities with a maturity comparable to the remaining term of the Securities. The investment banks from which the Company will select a Quotation Agent are BofA Securities, Inc., Citigroup Global Markets Inc. and Morgan Stanley & Co. LLC, or their

respective successors, or up to two other nationally recognized investment banking firms that are primary U.S. government securities dealers in New York City (each, a “Reference Treasury Dealer”). The Company will select one of the Reference Treasury Dealers to serve as its quotation agent (the “Quotation Agent”). If any of the firms referenced in the second preceding sentence ceases to be a primary dealer of U.S. government securities in New York City, the Company shall appoint another nationally recognized investment banking firm that is a primary dealer as a substitute.
“Comparable Treasury Price” means, for any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations given to the Trustee by the Reference Treasury Dealers for that Redemption Date after excluding the highest and lowest of those Reference Treasury Dealer Quotations (or only one of the highest or lowest of the Reference Treasury Dealer Quotations if there are more than one), or (2) if the Trustee is given fewer than four Reference Treasury Dealer Quotations, the average of all those quotations.
“Reference Treasury Dealer Quotation” means, with respect to any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the Trustee by a Reference Treasury Dealer as of 3:30 p.m., New York time, on the second Business Day preceding the date of the Redemption Notice. The Trustee shall seek Reference Treasury Dealer Quotations in respect of any Redemption Date from each of the then-existing Reference Treasury Dealers.
“Remaining Scheduled Payments” means, with respect to the principal amount of each Security being redeemed, the remaining scheduled payments of principal and interest on that Security that would be due after the related Redemption Date but for the redemption, assuming for such purpose that this Security matured on January 15, 2024. If, however, the Redemption Date is not an Interest Payment Date with respect to that Security, the amount of the next succeeding scheduled interest payment on that Security that would have been due will be deemed reduced by the amount of interest accrued on the Security to the Redemption Date.
On and after any Redemption Date, interest shall cease to accrue with respect to the Securities, or any portion of the Securities, called for redemption and for which the Redemption Price has been paid or made available for payment. On or prior to any Redemption Date, the Company shall deposit with the Paying Agent or the Trustee money sufficient to pay the Redemption Price on the Securities to be redeemed on such Redemption Date. If less than all of the Securities of this series are redeemed, the Trustee shall choose the Securities of this series to be redeemed by any method that it deems fair and appropriate, provided that if the Securities of this series are represented by one or more global Securities, interests in the Securities of this series will be selected for redemption by DTC in accordance with its standard procedures therefor.
Notwithstanding Section 1104 of the Indenture, the notice of any redemption referred to herein need not set forth the Redemption Price therefor but only the manner of calculation thereof. Promptly after the calculation of such Redemption Price, the Company shall give the Trustee notice thereof and the Trustee shall not be responsible for such calculation.

This Security is not repayable at the option of the Holder hereof and is not subject to the operation of any sinking fund.
If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.
The provisions of Section 1402 and Section 1403 of the Indenture relating to defeasance and covenant defeasance, respectively, shall apply to this Security. Pursuant to Section 1404(5) and Section 1404(6) of the Indenture, any such defeasance or covenant defeasance shall be conditioned on receipt of an Opinion of Counsel relating to the federal income tax consequences of such defeasance or covenant defeasance.
The Company will not pay any Additional Amounts to Holders that are not U.S. persons (including any modification to the definition of such term) in respect of any tax, assessment or governmental charge.
The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of all Securities at the time Outstanding to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Outstanding Securities, to waive compliance by the Company with certain provisions of the Indenture, and contains provisions permitting the Holders of specified percentages in principal amount, in certain instances of the Outstanding Securities of individual series and in other instances of all Securities at the time Outstanding, to waive on behalf of all of the Holders of Securities of such individual series or of the Holders of all Securities at the time Outstanding, as the case may be, certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.
As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount, in certain instances of the Securities of this series at the time Outstanding and in other instances of all Outstanding Securities, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of not less than a majority in principal amount of Securities of this series at the time Outstanding or of all Outstanding Securities, as the case may be, a direction inconsistent with such request, and shall have failed to

institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof (and premium, if any) or interest hereon on or after the respective due dates expressed herein.
No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or make provision as provided in Article Fourteen of the Indenture for the payment of the amount of principal of (and premium, if any) and interest on this Security herein provided, and at the times, place and rate, and in the coin or currency, herein prescribed.
As provided in the Indenture and subject to certain limitations therein and herein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.
The Securities of this series are issuable only in registered form without coupons in minimum denominations of $2,000 and any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series of a different authorized denomination, as requested by the Holder surrendering the same.
No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.
Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.
All terms used in this Security that are defined in the Indenture shall have the meanings assigned to them in the Indenture.

[REVERSE OF SECURITY]
This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Amended and Restated Indenture, dated as of May 1, 2001, as it may be supplemented from time to time (herein called the “Indenture”), between the Company (formerly known as United Technologies Corporation) and The Bank of New York Mellon Trust Company, N.A. (formerly The Bank of New York Trust Company, N.A.), as Trustee (successor to The Bank of New York) (herein called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the series of which this Security is a part), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof. The Indenture does not limit the aggregate principal amount of the Securities or the Securities of this series that may be issued thereunder. Additional Securities of this series may be issued from time to time hereafter; provided that any such additional Securities that are not fungible with this Security for U.S. federal income tax purposes will have a separate CUSIP, ISIN and other identifying number than this Security.
The Company may, at its option, redeem all or any part of this Security. If it chooses to do so, it shall mail or electronically deliver according to the procedures of DTC a notice of redemption (the “Redemption Notice”) to the Holder hereof (with a copy to the Trustee) not less than 15 days and not more than 60 days before the Redemption Date. If this Security is redeemed prior to January 15, 2024, the Redemption Price shall equal the greater of (i) 100% of the principal amount of this Security to be redeemed or (ii) the sum of the present values of the Remaining Scheduled Payments on the principal amount of this Security to be redeemed, assuming for such purpose that this Security matured on January 15, 2024, discounted to the Redemption Date on a semiannual basis, assuming a 360-day year consisting of twelve 30-day months, at the Treasury Rate plus 15 basis points. If this Security is redeemed on or after January 15, 2024, the Redemption Price shall be 100% of the principal amount of this Security to be redeemed. In each case, the Redemption Price shall also include interest accrued to, but excluding, the Redemption Date on the principal balance of this Security to be redeemed.
“Treasury Rate” means, for any Redemption Date, the annual rate equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue equal to the Comparable Treasury Price, expressed as a percentage of its principal amount, for that Redemption Date. The yield of the Comparable Treasury Issue will be computed as of the second Business Day immediately preceding the date of the Redemption Notice.
“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent (defined below) that has a maturity comparable to the remaining maturity of this Security (assuming, for this purpose, that this Security matured on January 15, 2024) and that would be used in accordance with customary financial practice to price new issues of corporate debt securities with a maturity comparable to the remaining term of the Securities. The investment banks from which the Company will select a Quotation Agent are BofA Securities, Inc., Citigroup Global Markets Inc. and Morgan Stanley & Co. LLC, or their

respective successors, or up to two other nationally recognized investment banking firms that are primary U.S. government securities dealers in New York City (each, a “Reference Treasury Dealer”). The Company will select one of the Reference Treasury Dealers to serve as its quotation agent (the “Quotation Agent”). If any of the firms referenced in the second preceding sentence ceases to be a primary dealer of U.S. government securities in New York City, the Company shall appoint another nationally recognized investment banking firm that is a primary dealer as a substitute.
“Comparable Treasury Price” means, for any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations given to the Trustee by the Reference Treasury Dealers for that Redemption Date after excluding the highest and lowest of those Reference Treasury Dealer Quotations (or only one of the highest or lowest of the Reference Treasury Dealer Quotations if there are more than one), or (2) if the Trustee is given fewer than four Reference Treasury Dealer Quotations, the average of all those quotations.
“Reference Treasury Dealer Quotation” means, with respect to any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the Trustee by a Reference Treasury Dealer as of 3:30 p.m., New York time, on the second Business Day preceding the date of the Redemption Notice. The Trustee shall seek Reference Treasury Dealer Quotations in respect of any Redemption Date from each of the then-existing Reference Treasury Dealers.
“Remaining Scheduled Payments” means, with respect to the principal amount of each Security being redeemed, the remaining scheduled payments of principal and interest on that Security that would be due after the related Redemption Date but for the redemption, assuming for such purpose that this Security matured on January 15, 2024. If, however, the Redemption Date is not an Interest Payment Date with respect to that Security, the amount of the next succeeding scheduled interest payment on that Security that would have been due will be deemed reduced by the amount of interest accrued on the Security to the Redemption Date.
On and after any Redemption Date, interest shall cease to accrue with respect to the Securities, or any portion of the Securities, called for redemption and for which the Redemption Price has been paid or made available for payment. On or prior to any Redemption Date, the Company shall deposit with the Paying Agent or the Trustee money sufficient to pay the Redemption Price on the Securities to be redeemed on such Redemption Date. If less than all of the Securities of this series are redeemed, the Trustee shall choose the Securities of this series to be redeemed by any method that it deems fair and appropriate, provided that if the Securities of this series are represented by one or more global Securities, interests in the Securities of this series will be selected for redemption by DTC in accordance with its standard procedures therefor.
Notwithstanding Section 1104 of the Indenture, the notice of any redemption referred to herein need not set forth the Redemption Price therefor but only the manner of calculation thereof. Promptly after the calculation of such Redemption Price, the Company shall give the Trustee notice thereof and the Trustee shall not be responsible for such calculation.

This Security is not repayable at the option of the Holder hereof and is not subject to the operation of any sinking fund.
If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.
The provisions of Section 1402 and Section 1403 of the Indenture relating to defeasance and covenant defeasance, respectively, shall apply to this Security. Pursuant to Section 1404(5) and Section 1404(6) of the Indenture, any such defeasance or covenant defeasance shall be conditioned on receipt of an Opinion of Counsel relating to the federal income tax consequences of such defeasance or covenant defeasance.
The Company will not pay any Additional Amounts to Holders that are not U.S. persons (including any modification to the definition of such term) in respect of any tax, assessment or governmental charge.
The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of all Securities at the time Outstanding to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Outstanding Securities, to waive compliance by the Company with certain provisions of the Indenture, and contains provisions permitting the Holders of specified percentages in principal amount, in certain instances of the Outstanding Securities of individual series and in other instances of all Securities at the time Outstanding, to waive on behalf of all of the Holders of Securities of such individual series or of the Holders of all Securities at the time Outstanding, as the case may be, certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.
As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount, in certain instances of the Securities of this series at the time Outstanding and in other instances of all Outstanding Securities, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of not less than a majority in principal amount of Securities of this series at the time Outstanding or of all Outstanding Securities, as the case may be, a direction inconsistent with such request, and shall have failed to

institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof (and premium, if any) or interest hereon on or after the respective due dates expressed herein.
No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or make provision as provided in Article Fourteen of the Indenture for the payment of the amount of principal of (and premium, if any) and interest on this Security herein provided, and at the times, place and rate, and in the coin or currency, herein prescribed.
As provided in the Indenture and subject to certain limitations therein and herein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.
The Securities of this series are issuable only in registered form without coupons in minimum denominations of $2,000 and any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series of a different authorized denomination, as requested by the Holder surrendering the same.
No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.
Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

(formerly The Bank of New York Trust Company, N.A.), as Trustee (successor to The Bank of New York) (herein called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the series of which this Security is a part), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered.

If it chooses to do so, it shall mail or electronically deliver according to the procedures of DTC a notice of redemption (the “Redemption Notice”) to the Holder hereof (with a copy to the Trustee) not less than 15 days and not more than 60 days before the Redemption Date.

If this Security is redeemed on or after December 15, 2026, the Redemption Price shall be 100% of the principal amount of this Security to be redeemed. In each case, the Redemption Price shall also include interest accrued to, but excluding, the Redemption Date on the principal balance of this Security to be redeemed.

“Remaining Scheduled Payments” means, with respect to the principal amount of each Security being redeemed, the remaining scheduled payments of principal and interest on that Security that would be due after the related Redemption Date but for the redemption, assuming for such purpose that this Security matured on December 15, 2026. If, however, the Redemption Date is not an Interest Payment Date with respect to that Security, the amount of the next succeeding scheduled interest payment on that Security that would have been due will be deemed reduced by the amount of interest accrued on the Security to the Redemption Date.
On and after any Redemption Date, interest shall cease to accrue with respect to the Securities, or any portion of the Securities, called for redemption and for which the Redemption Price has been paid or made available for payment. On or prior to any Redemption Date, the Company shall deposit with the Paying Agent or the Trustee money sufficient to pay the Redemption Price on the Securities to be redeemed on such Redemption Date. If less than all of the Securities of this series are redeemed, the Trustee shall choose the Securities of this series to be redeemed by any method that it deems fair and appropriate, provided that if the Securities of this series are represented by one or more global Securities, interests in the Securities of this series will be selected for redemption by DTC in accordance with its standard procedures therefor.

Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.
As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount, in certain instances of the Securities of this series at the time Outstanding and in other instances of all Outstanding Securities, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of not less than a majority in principal amount of Securities of this series at the time Outstanding or of all Outstanding Securities, as the case may be, a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof (and premium, if any) or interest hereon on or after the respective due dates expressed herein.

payment. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the date that is fifteen calendar days prior to the scheduled Interest Payment Date, regardless of whether such date is a Business Day; provided that if this Security is held by a securities depositary in book-entry form, such date shall be the close of business on the Business Day immediately preceding the Interest Payment Date (the “Regular Record Date”); provided, that interest payable on the maturity date or any Redemption Date will be payable to the Person to whom the principal of this Security is payable.

This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

|  |  | By: |
|  |  |  |  | Authorized Signatory

[REVERSE OF SECURITY]
This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Amended and Restated Indenture, dated as of May 1, 2001, as it may be supplemented from time to time (herein called the “Indenture”), between the Company (formerly known as United Technologies Corporation) and The Bank of New York Mellon Trust Company, N.A. (formerly The Bank of New York Trust Company, N.A.), as Trustee (successor to The Bank of New York) (herein called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the series of which this Security is a part), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof. The Indenture does not limit the aggregate principal amount of the Securities or the Securities of this series that may be issued thereunder. Additional Securities of this series may be issued from time to time hereafter; provided that any such additional Securities that are not fungible with this Security for U.S. federal income tax purposes will have a separate CUSIP, ISIN and other identifying number than this Security.
The Company may, at its option, redeem all or any part of this Security. If it chooses to do so, it shall mail or electronically deliver according to the procedures of DTC a notice of redemption (the “Redemption Notice”) to the Holder hereof (with a copy to the Trustee) not less than 15 days and not more than 60 days before the Redemption Date. If this Security is redeemed prior to December 15, 2026, the Redemption Price shall equal the greater of (i) 100% of the principal amount of this Security to be redeemed or (ii) the sum of the present values of the Remaining Scheduled Payments on the principal amount of this Security to be redeemed, assuming for such purpose that this Security matured on December 15, 2026, discounted to the Redemption Date on a semiannual basis, assuming a 360-day year consisting of twelve 30-day months, at the Treasury Rate plus 20 basis points. If this Security is redeemed on or after December 15, 2026, the Redemption Price shall be 100% of the principal amount of this Security to be redeemed. In each case, the Redemption Price shall also include interest accrued to, but excluding, the Redemption Date on the principal balance of this Security to be redeemed.
“Treasury Rate” means, for any Redemption Date, the annual rate equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue equal to the Comparable Treasury Price, expressed as a percentage of its principal amount, for that Redemption Date. The yield of the Comparable Treasury Issue will be computed as of the second Business Day immediately preceding the date of the Redemption Notice.
“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent (defined below) that has a maturity comparable to the remaining maturity of this Security (assuming, for this purpose, that this Security matured on December 15, 2026) and that would be used in accordance with customary financial practice to price new issues of corporate debt securities with a maturity comparable to the remaining term of the Securities. The investment banks from which the Company will select a Quotation Agent are BofA Securities, Inc., Citigroup Global Markets Inc. and Morgan Stanley & Co. LLC, or their

respective successors, or up to two other nationally recognized investment banking firms that are primary U.S. government securities dealers in New York City (each, a “Reference Treasury Dealer”). The Company will select one of the Reference Treasury Dealers to serve as its quotation agent (the “Quotation Agent”). If any of the firms referenced in the second preceding sentence ceases to be a primary dealer of U.S. government securities in New York City, the Company shall appoint another nationally recognized investment banking firm that is a primary dealer as a substitute.
“Comparable Treasury Price” means, for any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations given to the Trustee by the Reference Treasury Dealers for that Redemption Date after excluding the highest and lowest of those Reference Treasury Dealer Quotations (or only one of the highest or lowest of the Reference Treasury Dealer Quotations if there are more than one), or (2) if the Trustee is given fewer than four Reference Treasury Dealer Quotations, the average of all those quotations.
“Reference Treasury Dealer Quotation” means, with respect to any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the Trustee by a Reference Treasury Dealer as of 3:30 p.m., New York time, on the second Business Day preceding the date of the Redemption Notice. The Trustee shall seek Reference Treasury Dealer Quotations in respect of any Redemption Date from each of the then-existing Reference Treasury Dealers.
“Remaining Scheduled Payments” means, with respect to the principal amount of each Security being redeemed, the remaining scheduled payments of principal and interest on that Security that would be due after the related Redemption Date but for the redemption, assuming for such purpose that this Security matured on December 15, 2026. If, however, the Redemption Date is not an Interest Payment Date with respect to that Security, the amount of the next succeeding scheduled interest payment on that Security that would have been due will be deemed reduced by the amount of interest accrued on the Security to the Redemption Date.
On and after any Redemption Date, interest shall cease to accrue with respect to the Securities, or any portion of the Securities, called for redemption and for which the Redemption Price has been paid or made available for payment. On or prior to any Redemption Date, the Company shall deposit with the Paying Agent or the Trustee money sufficient to pay the Redemption Price on the Securities to be redeemed on such Redemption Date. If less than all of the Securities of this series are redeemed, the Trustee shall choose the Securities of this series to be redeemed by any method that it deems fair and appropriate, provided that if the Securities of this series are represented by one or more global Securities, interests in the Securities of this series will be selected for redemption by DTC in accordance with its standard procedures therefor.
Notwithstanding Section 1104 of the Indenture, the notice of any redemption referred to herein need not set forth the Redemption Price therefor but only the manner of calculation thereof. Promptly after the calculation of such Redemption Price, the Company shall give the Trustee notice thereof and the Trustee shall not be responsible for such calculation.

This Security is not repayable at the option of the Holder hereof and is not subject to the operation of any sinking fund.
If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.
The provisions of Section 1402 and Section 1403 of the Indenture relating to defeasance and covenant defeasance, respectively, shall apply to this Security. Pursuant to Section 1404(5) and Section 1404(6) of the Indenture, any such defeasance or covenant defeasance shall be conditioned on receipt of an Opinion of Counsel relating to the federal income tax consequences of such defeasance or covenant defeasance.
The Company will not pay any Additional Amounts to Holders that are not U.S. persons (including any modification to the definition of such term) in respect of any tax, assessment or governmental charge.
The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of all Securities at the time Outstanding to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Outstanding Securities, to waive compliance by the Company with certain provisions of the Indenture, and contains provisions permitting the Holders of specified percentages in principal amount, in certain instances of the Outstanding Securities of individual series and in other instances of all Securities at the time Outstanding, to waive on behalf of all of the Holders of Securities of such individual series or of the Holders of all Securities at the time Outstanding, as the case may be, certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.
As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount, in certain instances of the Securities of this series at the time Outstanding and in other instances of all Outstanding Securities, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of not less than a majority in principal amount of Securities of this series at the time Outstanding or of all Outstanding Securities, as the case may be, a direction inconsistent with such request, and shall have failed to

institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof (and premium, if any) or interest hereon on or after the respective due dates expressed herein.
No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or make provision as provided in Article Fourteen of the Indenture for the payment of the amount of principal of (and premium, if any) and interest on this Security herein provided, and at the times, place and rate, and in the coin or currency, herein prescribed.
As provided in the Indenture and subject to certain limitations therein and herein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.
The Securities of this series are issuable only in registered form without coupons in minimum denominations of $2,000 and any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series of a different authorized denomination, as requested by the Holder surrendering the same.
No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.
Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

TRUSTEE’S CERTIFICATE OF AUTHENTICATION
This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

|  |  | THE BANK OF NEW YORK MELLON TRUST COMPANY, N.A., as Trustee
|  |  | By: |
|  |  |  |  | Authorized Signatory
Dated: |  |  |  |  |

[REVERSE OF SECURITY]
This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Amended and Restated Indenture, dated as of May 1, 2001, as it may be supplemented from time to time (herein called the “Indenture”), between the Company (formerly known as United Technologies Corporation) and The Bank of New York Mellon Trust Company, N.A. (formerly The Bank of New York Trust Company, N.A.), as Trustee (successor to The Bank of New York) (herein called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the series of which this Security is a part), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof. The Indenture does not limit the aggregate principal amount of the Securities or the Securities of this series that may be issued thereunder. Additional Securities of this series may be issued from time to time hereafter; provided that any such additional Securities that are not fungible with this Security for U.S. federal income tax purposes will have a separate CUSIP, ISIN and other identifying number than this Security.
The Company may, at its option, redeem all or any part of this Security. If it chooses to do so, it shall mail or electronically deliver according to the procedures of DTC a notice of redemption (the “Redemption Notice”) to the Holder hereof (with a copy to the Trustee) not less than 15 days and not more than 60 days before the Redemption Date. If this Security is redeemed prior to December 15, 2026, the Redemption Price shall equal the greater of (i) 100% of the principal amount of this Security to be redeemed or (ii) the sum of the present values of the Remaining Scheduled Payments on the principal amount of this Security to be redeemed, assuming for such purpose that this Security matured on December 15, 2026, discounted to the Redemption Date on a semiannual basis, assuming a 360-day year consisting of twelve 30-day months, at the Treasury Rate plus 20 basis points. If this Security is redeemed on or after December 15, 2026, the Redemption Price shall be 100% of the principal amount of this Security to be redeemed. In each case, the Redemption Price shall also include interest accrued to, but excluding, the Redemption Date on the principal balance of this Security to be redeemed.
“Treasury Rate” means, for any Redemption Date, the annual rate equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue equal to the Comparable Treasury Price, expressed as a percentage of its principal amount, for that Redemption Date. The yield of the Comparable Treasury Issue will be computed as of the second Business Day immediately preceding the date of the Redemption Notice.
“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent (defined below) that has a maturity comparable to the remaining maturity of this Security (assuming, for this purpose, that this Security matured on December 15, 2026) and that would be used in accordance with customary financial practice to price new issues of corporate debt securities with a maturity comparable to the remaining term of the Securities. The investment banks from which the Company will select a Quotation Agent are BofA Securities, Inc., Citigroup Global Markets Inc. and Morgan Stanley & Co. LLC, or their

respective successors, or up to two other nationally recognized investment banking firms that are primary U.S. government securities dealers in New York City (each, a “Reference Treasury Dealer”). The Company will select one of the Reference Treasury Dealers to serve as its quotation agent (the “Quotation Agent”). If any of the firms referenced in the second preceding sentence ceases to be a primary dealer of U.S. government securities in New York City, the Company shall appoint another nationally recognized investment banking firm that is a primary dealer as a substitute.
“Comparable Treasury Price” means, for any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations given to the Trustee by the Reference Treasury Dealers for that Redemption Date after excluding the highest and lowest of those Reference Treasury Dealer Quotations (or only one of the highest or lowest of the Reference Treasury Dealer Quotations if there are more than one), or (2) if the Trustee is given fewer than four Reference Treasury Dealer Quotations, the average of all those quotations.
“Reference Treasury Dealer Quotation” means, with respect to any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the Trustee by a Reference Treasury Dealer as of 3:30 p.m., New York time, on the second Business Day preceding the date of the Redemption Notice. The Trustee shall seek Reference Treasury Dealer Quotations in respect of any Redemption Date from each of the then-existing Reference Treasury Dealers.
“Remaining Scheduled Payments” means, with respect to the principal amount of each Security being redeemed, the remaining scheduled payments of principal and interest on that Security that would be due after the related Redemption Date but for the redemption, assuming for such purpose that this Security matured on December 15, 2026. If, however, the Redemption Date is not an Interest Payment Date with respect to that Security, the amount of the next succeeding scheduled interest payment on that Security that would have been due will be deemed reduced by the amount of interest accrued on the Security to the Redemption Date.
On and after any Redemption Date, interest shall cease to accrue with respect to the Securities, or any portion of the Securities, called for redemption and for which the Redemption Price has been paid or made available for payment. On or prior to any Redemption Date, the Company shall deposit with the Paying Agent or the Trustee money sufficient to pay the Redemption Price on the Securities to be redeemed on such Redemption Date. If less than all of the Securities of this series are redeemed, the Trustee shall choose the Securities of this series to be redeemed by any method that it deems fair and appropriate, provided that if the Securities of this series are represented by one or more global Securities, interests in the Securities of this series will be selected for redemption by DTC in accordance with its standard procedures therefor.
Notwithstanding Section 1104 of the Indenture, the notice of any redemption referred to herein need not set forth the Redemption Price therefor but only the manner of calculation thereof. Promptly after the calculation of such Redemption Price, the Company shall give the Trustee notice thereof and the Trustee shall not be responsible for such calculation.

This Security is not repayable at the option of the Holder hereof and is not subject to the operation of any sinking fund.
If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.
The provisions of Section 1402 and Section 1403 of the Indenture relating to defeasance and covenant defeasance, respectively, shall apply to this Security. Pursuant to Section 1404(5) and Section 1404(6) of the Indenture, any such defeasance or covenant defeasance shall be conditioned on receipt of an Opinion of Counsel relating to the federal income tax consequences of such defeasance or covenant defeasance.
The Company will not pay any Additional Amounts to Holders that are not U.S. persons (including any modification to the definition of such term) in respect of any tax, assessment or governmental charge.
The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of all Securities at the time Outstanding to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Outstanding Securities, to waive compliance by the Company with certain provisions of the Indenture, and contains provisions permitting the Holders of specified percentages in principal amount, in certain instances of the Outstanding Securities of individual series and in other instances of all Securities at the time Outstanding, to waive on behalf of all of the Holders of Securities of such individual series or of the Holders of all Securities at the time Outstanding, as the case may be, certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.
As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount, in certain instances of the Securities of this series at the time Outstanding and in other instances of all Outstanding Securities, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of not less than a majority in principal amount of Securities of this series at the time Outstanding or of all Outstanding Securities, as the case may be, a direction inconsistent with such request, and shall have failed to

institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof (and premium, if any) or interest hereon on or after the respective due dates expressed herein.
No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or make provision as provided in Article Fourteen of the Indenture for the payment of the amount of principal of (and premium, if any) and interest on this Security herein provided, and at the times, place and rate, and in the coin or currency, herein prescribed.
As provided in the Indenture and subject to certain limitations therein and herein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.
The Securities of this series are issuable only in registered form without coupons in minimum denominations of $2,000 and any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series of a different authorized denomination, as requested by the Holder surrendering the same.
No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.
Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

(formerly The Bank of New York Trust Company, N.A.), as Trustee (successor to The Bank of New York) (herein called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the series of which this Security is a part), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof. The Indenture does not limit the aggregate principal amount of the Securities or the Securities of this series that may be issued thereunder. Additional Securities of this series may be issued from time to time hereafter; provided that any such additional Securities that are not fungible with this Security for U.S. federal income tax purposes will have a separate CUSIP, ISIN and other identifying number than this Security.
The Company may, at its option, redeem all or any part of this Security. If it chooses to do so, it shall mail or electronically deliver according to the procedures of DTC a notice of redemption (the “Redemption Notice”) to the Holder hereof (with a copy to the Trustee) not less than 15 days and not more than 60 days before the Redemption Date. If this Security is redeemed prior to December 15, 2026, the Redemption Price shall equal the greater of (i) 100% of the principal amount of this Security to be redeemed or (ii) the sum of the present values of the Remaining Scheduled Payments on the principal amount of this Security to be redeemed, assuming for such purpose that this Security matured on December 15, 2026, discounted to the Redemption Date on a semiannual basis, assuming a 360-day year consisting of twelve 30-day months, at the Treasury Rate plus 20 basis points. If this Security is redeemed on or after December 15, 2026, the Redemption Price shall be 100% of the principal amount of this Security to be redeemed. In each case, the Redemption Price shall also include interest accrued to, but excluding, the Redemption Date on the principal balance of this Security to be redeemed.
“Treasury Rate” means, for any Redemption Date, the annual rate equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue equal to the Comparable Treasury Price, expressed as a percentage of its principal amount, for that Redemption Date. The yield of the Comparable Treasury Issue will be computed as of the second Business Day immediately preceding the date of the Redemption Notice.
“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent (defined below) that has a maturity comparable to the remaining maturity of this Security (assuming, for this purpose, that this Security matured on December 15, 2026) and that would be used in accordance with customary financial practice to price new issues of corporate debt securities with a maturity comparable to the remaining term of the Securities. The investment banks from which the Company will select a Quotation Agent are BofA Securities, Inc., Citigroup Global Markets Inc. and Morgan Stanley & Co. LLC, or their

respective successors, or up to two other nationally recognized investment banking firms that are primary U.S. government securities dealers in New York City (each, a “Reference Treasury Dealer”). The Company will select one of the Reference Treasury Dealers to serve as its quotation agent (the “Quotation Agent”). If any of the firms referenced in the second preceding sentence ceases to be a primary dealer of U.S. government securities in New York City, the Company shall appoint another nationally recognized investment banking firm that is a primary dealer as a substitute.
“Comparable Treasury Price” means, for any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations given to the Trustee by the Reference Treasury Dealers for that Redemption Date after excluding the highest and lowest of those Reference Treasury Dealer Quotations (or only one of the highest or lowest of the Reference Treasury Dealer Quotations if there are more than one), or (2) if the Trustee is given fewer than four Reference Treasury Dealer Quotations, the average of all those quotations.
“Reference Treasury Dealer Quotation” means, with respect to any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the Trustee by a Reference Treasury Dealer as of 3:30 p.m., New York time, on the second Business Day preceding the date of the Redemption Notice. The Trustee shall seek Reference Treasury Dealer Quotations in respect of any Redemption Date from each of the then-existing Reference Treasury Dealers.
“Remaining Scheduled Payments” means, with respect to the principal amount of each Security being redeemed, the remaining scheduled payments of principal and interest on that Security that would be due after the related Redemption Date but for the redemption, assuming for such purpose that this Security matured on December 15, 2026. If, however, the Redemption Date is not an Interest Payment Date with respect to that Security, the amount of the next succeeding scheduled interest payment on that Security that would have been due will be deemed reduced by the amount of interest accrued on the Security to the Redemption Date.
On and after any Redemption Date, interest shall cease to accrue with respect to the Securities, or any portion of the Securities, called for redemption and for which the Redemption Price has been paid or made available for payment. On or prior to any Redemption Date, the Company shall deposit with the Paying Agent or the Trustee money sufficient to pay the Redemption Price on the Securities to be redeemed on such Redemption Date. If less than all of the Securities of this series are redeemed, the Trustee shall choose the Securities of this series to be redeemed by any method that it deems fair and appropriate, provided that if the Securities of this series are represented by one or more global Securities, interests in the Securities of this series will be selected for redemption by DTC in accordance with its standard procedures therefor.
Notwithstanding Section 1104 of the Indenture, the notice of any redemption referred to herein need not set forth the Redemption Price therefor but only the manner of calculation thereof. Promptly after the calculation of such Redemption Price, the Company shall give the Trustee notice thereof and the Trustee shall not be responsible for such calculation.

This Security is not repayable at the option of the Holder hereof and is not subject to the operation of any sinking fund.
If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.
The provisions of Section 1402 and Section 1403 of the Indenture relating to defeasance and covenant defeasance, respectively, shall apply to this Security. Pursuant to Section 1404(5) and Section 1404(6) of the Indenture, any such defeasance or covenant defeasance shall be conditioned on receipt of an Opinion of Counsel relating to the federal income tax consequences of such defeasance or covenant defeasance.
The Company will not pay any Additional Amounts to Holders that are not U.S. persons (including any modification to the definition of such term) in respect of any tax, assessment or governmental charge.
The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of all Securities at the time Outstanding to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Outstanding Securities, to waive compliance by the Company with certain provisions of the Indenture, and contains provisions permitting the Holders of specified percentages in principal amount, in certain instances of the Outstanding Securities of individual series and in other instances of all Securities at the time Outstanding, to waive on behalf of all of the Holders of Securities of such individual series or of the Holders of all Securities at the time Outstanding, as the case may be, certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.
As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount, in certain instances of the Securities of this series at the time Outstanding and in other instances of all Outstanding Securities, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of not less than a majority in principal amount of Securities of this series at the time Outstanding or of all Outstanding Securities, as the case may be, a direction inconsistent with such request, and shall have failed to

institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof (and premium, if any) or interest hereon on or after the respective due dates expressed herein.
No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or make provision as provided in Article Fourteen of the Indenture for the payment of the amount of principal of (and premium, if any) and interest on this Security herein provided, and at the times, place and rate, and in the coin or currency, herein prescribed.
As provided in the Indenture and subject to certain limitations therein and herein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.
The Securities of this series are issuable only in registered form without coupons in minimum denominations of $2,000 and any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series of a different authorized denomination, as requested by the Holder surrendering the same.
No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.
Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

[REVERSE OF SECURITY]
This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Amended and Restated Indenture, dated as of May 1, 2001, as it may be supplemented from time to time (herein called the “Indenture”), between the Company (formerly known as United Technologies Corporation) and The Bank of New York Mellon Trust Company, N.A. (formerly The Bank of New York Trust Company, N.A.), as Trustee (successor to The Bank of New York) (herein called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the series of which this Security is a part), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof. The Indenture does not limit the aggregate principal amount of the Securities or the Securities of this series that may be issued thereunder. Additional Securities of this series may be issued from time to time hereafter; provided that any such additional Securities that are not fungible with this Security for U.S. federal income tax purposes will have a separate CUSIP, ISIN and other identifying number than this Security.
The Company may, at its option, redeem all or any part of this Security. If it chooses to do so, it shall mail or electronically deliver according to the procedures of DTC a notice of redemption (the “Redemption Notice”) to the Holder hereof (with a copy to the Trustee) not less than 15 days and not more than 60 days before the Redemption Date. If this Security is redeemed prior to June 15, 2043, the Redemption Price shall equal the greater of (i) 100% of the principal amount of this Security to be redeemed or (ii) the sum of the present values of the Remaining Scheduled Payments on the principal amount of this Security to be redeemed, assuming for such purpose that this Security matured on June 15, 2043, discounted to the Redemption Date on a semiannual basis, assuming a 360-day year consisting of twelve 30-day months, at the Treasury Rate plus 15 basis points. If this Security is redeemed on or after June 15, 2043, the Redemption Price shall be 100% of the principal amount of this Security to be redeemed. In each case, the Redemption Price shall also include interest accrued to, but excluding, the Redemption Date on the principal balance of this Security to be redeemed.
“Treasury Rate” means, for any Redemption Date, the annual rate equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue equal to the Comparable Treasury Price, expressed as a percentage of its principal amount, for that Redemption Date. The yield of the Comparable Treasury Issue will be computed as of the second Business Day immediately preceding the date of the Redemption Notice.
“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent (defined below) that has a maturity comparable to the remaining maturity of this Security (assuming, for this purpose, that this Security matured on June 15, 2043) and that would be used in accordance with customary financial practice to price new issues of corporate debt securities with a maturity comparable to the remaining term of the Securities. The investment banks from which the Company will select a Quotation Agent are BofA Securities, Inc., Citigroup Global Markets Inc. and Morgan Stanley & Co. LLC, or their

respective successors, or up to two other nationally recognized investment banking firms that are primary U.S. government securities dealers in New York City (each, a “Reference Treasury Dealer”). The Company will select one of the Reference Treasury Dealers to serve as its quotation agent (the “Quotation Agent”). If any of the firms referenced in the second preceding sentence ceases to be a primary dealer of U.S. government securities in New York City, the Company shall appoint another nationally recognized investment banking firm that is a primary dealer as a substitute.
“Comparable Treasury Price” means, for any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations given to the Trustee by the Reference Treasury Dealers for that Redemption Date after excluding the highest and lowest of those Reference Treasury Dealer Quotations (or only one of the highest or lowest of the Reference Treasury Dealer Quotations if there are more than one), or (2) if the Trustee is given fewer than four Reference Treasury Dealer Quotations, the average of all those quotations.
“Reference Treasury Dealer Quotation” means, with respect to any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the Trustee by a Reference Treasury Dealer as of 3:30 p.m., New York time, on the second Business Day preceding the date of the Redemption Notice. The Trustee shall seek Reference Treasury Dealer Quotations in respect of any Redemption Date from each of the then-existing Reference Treasury Dealers.
“Remaining Scheduled Payments” means, with respect to the principal amount of each Security being redeemed, the remaining scheduled payments of principal and interest on that Security that would be due after the related Redemption Date but for the redemption, assuming for such purpose that this Security matured on June 15, 2043. If, however, the Redemption Date is not an Interest Payment Date with respect to that Security, the amount of the next succeeding scheduled interest payment on that Security that would have been due will be deemed reduced by the amount of interest accrued on the Security to the Redemption Date.
On and after any Redemption Date, interest shall cease to accrue with respect to the Securities, or any portion of the Securities, called for redemption and for which the Redemption Price has been paid or made available for payment. On or prior to any Redemption Date, the Company shall deposit with the Paying Agent or the Trustee money sufficient to pay the Redemption Price on the Securities to be redeemed on such Redemption Date. If less than all of the Securities of this series are redeemed, the Trustee shall choose the Securities of this series to be redeemed by any method that it deems fair and appropriate, provided that if the Securities of this series are represented by one or more global Securities, interests in the Securities of this series will be selected for redemption by DTC in accordance with its standard procedures therefor.
Notwithstanding Section 1104 of the Indenture, the notice of any redemption referred to herein need not set forth the Redemption Price therefor but only the manner of calculation thereof. Promptly after the calculation of such Redemption Price, the Company shall give the Trustee notice thereof and the Trustee shall not be responsible for such calculation.

This Security is not repayable at the option of the Holder hereof and is not subject to the operation of any sinking fund.
If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.
The provisions of Section 1402 and Section 1403 of the Indenture relating to defeasance and covenant defeasance, respectively, shall apply to this Security. Pursuant to Section 1404(5) and Section 1404(6) of the Indenture, any such defeasance or covenant defeasance shall be conditioned on receipt of an Opinion of Counsel relating to the federal income tax consequences of such defeasance or covenant defeasance.
The Company will not pay any Additional Amounts to Holders that are not U.S. persons (including any modification to the definition of such term) in respect of any tax, assessment or governmental charge.
The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of all Securities at the time Outstanding to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Outstanding Securities, to waive compliance by the Company with certain provisions of the Indenture, and contains provisions permitting the Holders of specified percentages in principal amount, in certain instances of the Outstanding Securities of individual series and in other instances of all Securities at the time Outstanding, to waive on behalf of all of the Holders of Securities of such individual series or of the Holders of all Securities at the time Outstanding, as the case may be, certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.
As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount, in certain instances of the Securities of this series at the time Outstanding and in other instances of all Outstanding Securities, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of not less than a majority in principal amount of Securities of this series at the time Outstanding or of all Outstanding Securities, as the case may be, a direction inconsistent with such request, and shall have failed to

registered assigns, the principal sum of NINETY-SEVEN THOUSAND DOLLARS ($97,000) on December 15, 2043, and to pay interest thereon (computed on the basis of a 360-day year comprised of twelve 30-day months) from December 15, 2019 or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semiannually in arrears on June 15 and December 15 of each year, and on the maturity date, commencing on June 15, 2020, at the rate of 4.800% per annum, until the principal hereof is paid or made available for payment. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the date that is fifteen calendar days prior to the scheduled Interest Payment Date, regardless of whether such date is a Business Day; provided that if this Security is held by a securities depositary in book-entry form, such date shall be the close of business on the Business Day immediately preceding the Interest Payment Date (the “Regular Record Date”); provided, that interest payable on the maturity date or any Redemption Date will be payable to the Person to whom the principal of this Security is payable.

[REVERSE OF SECURITY]
This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Amended and Restated Indenture, dated as of May 1, 2001, as it may be supplemented from time to time (herein called the “Indenture”), between the Company (formerly known as United Technologies Corporation) and The Bank of New York Mellon Trust Company, N.A. (formerly The Bank of New York Trust Company, N.A.), as Trustee (successor to The Bank of New York) (herein called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the series of which this Security is a part), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof. The Indenture does not limit the aggregate principal amount of the Securities or the Securities of this series that may be issued thereunder. Additional Securities of this series may be issued from time to time hereafter; provided that any such additional Securities that are not fungible with this Security for U.S. federal income tax purposes will have a separate CUSIP, ISIN and other identifying number than this Security.
The Company may, at its option, redeem all or any part of this Security. If it chooses to do so, it shall mail or electronically deliver according to the procedures of DTC a notice of redemption (the “Redemption Notice”) to the Holder hereof (with a copy to the Trustee) not less than 15 days and not more than 60 days before the Redemption Date. If this Security is redeemed prior to June 15, 2043, the Redemption Price shall equal the greater of (i) 100% of the principal amount of this Security to be redeemed or (ii) the sum of the present values of the Remaining Scheduled Payments on the principal amount of this Security to be redeemed, assuming for such purpose that this Security matured on June 15, 2043, discounted to the Redemption Date on a semiannual basis, assuming a 360-day year consisting of twelve 30-day months, at the Treasury Rate plus 15 basis points. If this Security is redeemed on or after June 15, 2043, the Redemption Price shall be 100% of the principal amount of this Security to be redeemed. In each case, the Redemption Price shall also include interest accrued to, but excluding, the Redemption Date on the principal balance of this Security to be redeemed.
“Treasury Rate” means, for any Redemption Date, the annual rate equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue equal to the Comparable Treasury Price, expressed as a percentage of its principal amount, for that Redemption Date. The yield of the Comparable Treasury Issue will be computed as of the second Business Day immediately preceding the date of the Redemption Notice.
“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent (defined below) that has a maturity comparable to the remaining maturity of this Security (assuming, for this purpose, that this Security matured on June 15, 2043) and that would be used in accordance with customary financial practice to price new issues of corporate debt securities with a maturity comparable to the remaining term of the Securities. The investment banks from which the Company will select a Quotation Agent are BofA Securities, Inc., Citigroup Global Markets Inc. and Morgan Stanley & Co. LLC, or their

respective successors, or up to two other nationally recognized investment banking firms that are primary U.S. government securities dealers in New York City (each, a “Reference Treasury Dealer”). The Company will select one of the Reference Treasury Dealers to serve as its quotation agent (the “Quotation Agent”). If any of the firms referenced in the second preceding sentence ceases to be a primary dealer of U.S. government securities in New York City, the Company shall appoint another nationally recognized investment banking firm that is a primary dealer as a substitute.
“Comparable Treasury Price” means, for any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations given to the Trustee by the Reference Treasury Dealers for that Redemption Date after excluding the highest and lowest of those Reference Treasury Dealer Quotations (or only one of the highest or lowest of the Reference Treasury Dealer Quotations if there are more than one), or (2) if the Trustee is given fewer than four Reference Treasury Dealer Quotations, the average of all those quotations.
“Reference Treasury Dealer Quotation” means, with respect to any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the Trustee by a Reference Treasury Dealer as of 3:30 p.m., New York time, on the second Business Day preceding the date of the Redemption Notice. The Trustee shall seek Reference Treasury Dealer Quotations in respect of any Redemption Date from each of the then-existing Reference Treasury Dealers.
“Remaining Scheduled Payments” means, with respect to the principal amount of each Security being redeemed, the remaining scheduled payments of principal and interest on that Security that would be due after the related Redemption Date but for the redemption, assuming for such purpose that this Security matured on June 15, 2043. If, however, the Redemption Date is not an Interest Payment Date with respect to that Security, the amount of the next succeeding scheduled interest payment on that Security that would have been due will be deemed reduced by the amount of interest accrued on the Security to the Redemption Date.
On and after any Redemption Date, interest shall cease to accrue with respect to the Securities, or any portion of the Securities, called for redemption and for which the Redemption Price has been paid or made available for payment. On or prior to any Redemption Date, the Company shall deposit with the Paying Agent or the Trustee money sufficient to pay the Redemption Price on the Securities to be redeemed on such Redemption Date. If less than all of the Securities of this series are redeemed, the Trustee shall choose the Securities of this series to be redeemed by any method that it deems fair and appropriate, provided that if the Securities of this series are represented by one or more global Securities, interests in the Securities of this series will be selected for redemption by DTC in accordance with its standard procedures therefor.
Notwithstanding Section 1104 of the Indenture, the notice of any redemption referred to herein need not set forth the Redemption Price therefor but only the manner of calculation thereof. Promptly after the calculation of such Redemption Price, the Company shall give the Trustee notice thereof and the Trustee shall not be responsible for such calculation.

This Security is not repayable at the option of the Holder hereof and is not subject to the operation of any sinking fund.
If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.
The provisions of Section 1402 and Section 1403 of the Indenture relating to defeasance and covenant defeasance, respectively, shall apply to this Security. Pursuant to Section 1404(5) and Section 1404(6) of the Indenture, any such defeasance or covenant defeasance shall be conditioned on receipt of an Opinion of Counsel relating to the federal income tax consequences of such defeasance or covenant defeasance.
The Company will not pay any Additional Amounts to Holders that are not U.S. persons (including any modification to the definition of such term) in respect of any tax, assessment or governmental charge.
The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of all Securities at the time Outstanding to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Outstanding Securities, to waive compliance by the Company with certain provisions of the Indenture, and contains provisions permitting the Holders of specified percentages in principal amount, in certain instances of the Outstanding Securities of individual series and in other instances of all Securities at the time Outstanding, to waive on behalf of all of the Holders of Securities of such individual series or of the Holders of all Securities at the time Outstanding, as the case may be, certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.
As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount, in certain instances of the Securities of this series at the time Outstanding and in other instances of all Outstanding Securities, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of not less than a majority in principal amount of Securities of this series at the time Outstanding or of all Outstanding Securities, as the case may be, a direction inconsistent with such request, and shall have failed to

institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof (and premium, if any) or interest hereon on or after the respective due dates expressed herein.
No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or make provision as provided in Article Fourteen of the Indenture for the payment of the amount of principal of (and premium, if any) and interest on this Security herein provided, and at the times, place and rate, and in the coin or currency, herein prescribed.
As provided in the Indenture and subject to certain limitations therein and herein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.
The Securities of this series are issuable only in registered form without coupons in minimum denominations of $2,000 and any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series of a different authorized denomination, as requested by the Holder surrendering the same.
No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.
Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

TRUSTEE’S CERTIFICATE OF AUTHENTICATION
This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

| THE BANK OF NEW YORK MELLON TRUST COMPANY, N.A., as Trustee
| By: |
|  | Authorized Signatory

Dated: _____________________

[REVERSE OF SECURITY]
This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Amended and Restated Indenture, dated as of May 1, 2001, as it may be supplemented from time to time (herein called the “Indenture”), between the Company (formerly known as United Technologies Corporation) and The Bank of New York Mellon Trust Company, N.A. (formerly The Bank of New York Trust Company, N.A.), as Trustee (successor to The Bank of New York) (herein called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the series of which this Security is a part), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof. The Indenture does not limit the aggregate principal amount of the Securities or the Securities of this series that may be issued thereunder. Additional Securities of this series may be issued from time to time hereafter; provided that any such additional Securities that are not fungible with this Security for U.S. federal income tax purposes will have a separate CUSIP, ISIN and other identifying number than this Security.
The Company may, at its option, redeem all or any part of this Security. If it chooses to do so, it shall mail or electronically deliver according to the procedures of DTC a notice of redemption (the “Redemption Notice”) to the Holder hereof (with a copy to the Trustee) not less than 15 days and not more than 60 days before the Redemption Date. If this Security is redeemed prior to October 15, 2046, the Redemption Price shall equal the greater of (i) 100% of the principal amount of this Security to be redeemed or (ii) the sum of the present values of the Remaining Scheduled Payments on the principal amount of this Security to be redeemed, assuming for such purpose that this Security matured on October 15, 2046, discounted to the Redemption Date on a semiannual basis, assuming a 360-day year consisting of twelve 30-day months, at the Treasury Rate plus 25 basis points. If this Security is redeemed on or after October 15, 2046, the Redemption Price shall be 100% of the principal amount of this Security to be redeemed. In each case, the Redemption Price shall also include interest accrued to, but excluding, the Redemption Date on the principal balance of this Security to be redeemed.
“Treasury Rate” means, for any Redemption Date, the annual rate equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue equal to the Comparable Treasury Price, expressed as a percentage of its principal amount, for that Redemption Date. The yield of the Comparable Treasury Issue will be computed as of the second Business Day immediately preceding the date of the Redemption Notice.
“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent (defined below) that has a maturity comparable to the remaining maturity of this Security (assuming, for this purpose, that this Security matured on October 15, 2046) and that would be used in accordance with customary financial practice to price new issues of corporate debt securities with a maturity comparable to the remaining term of the Securities. The investment banks from which the Company will select a Quotation Agent are BofA Securities, Inc., Citigroup Global Markets Inc. and Morgan Stanley & Co. LLC, or their respective successors, or up to two other nationally recognized investment banking firms that are primary U.S. government securities dealers in New York City (each, a “Reference Treasury Dealer”). The Company will select one of the Reference Treasury Dealers to serve as its quotation agent (the “Quotation Agent”). If any of the firms referenced in the second preceding sentence ceases to be a primary dealer of U.S. government securities in New York City, the Company shall appoint another nationally recognized investment banking firm that is a primary dealer as a substitute.

“Comparable Treasury Price” means, for any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations given to the Trustee by the Reference Treasury Dealers for that Redemption Date after excluding the highest and lowest of those Reference Treasury Dealer Quotations (or only one of the highest or lowest of the Reference Treasury Dealer Quotations if there are more than one), or (2) if the Trustee is given fewer than four Reference Treasury Dealer Quotations, the average of all those quotations.
“Reference Treasury Dealer Quotation” means, with respect to any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the Trustee by a Reference Treasury Dealer as of 3:30 p.m., New York time, on the second Business Day preceding the date of the Redemption Notice. The Trustee shall seek Reference Treasury Dealer Quotations in respect of any Redemption Date from each of the then-existing Reference Treasury Dealers.
“Remaining Scheduled Payments” means, with respect to the principal amount of each Security being redeemed, the remaining scheduled payments of principal and interest on that Security that would be due after the related Redemption Date but for the redemption, assuming for such purpose that this Security matured on October 15, 2046. If, however, the Redemption Date is not an Interest Payment Date with respect to that Security, the amount of the next succeeding scheduled interest payment on that Security that would have been due will be deemed reduced by the amount of interest accrued on the Security to the Redemption Date.
On and after any Redemption Date, interest shall cease to accrue with respect to the Securities, or any portion of the Securities, called for redemption and for which the Redemption Price has been paid or made available for payment. On or prior to any Redemption Date, the Company shall deposit with the Paying Agent or the Trustee money sufficient to pay the Redemption Price on the Securities to be redeemed on such Redemption Date. If less than all of the Securities of this series are redeemed, the Trustee shall choose the Securities of this series to be redeemed by any method that it deems fair and appropriate, provided that if the Securities of this series are represented by one or more global Securities, interests in the Securities of this series will be selected for redemption by DTC in accordance with its standard procedures therefor.
Notwithstanding Section 1104 of the Indenture, the notice of any redemption referred to herein need not set forth the Redemption Price therefor but only the manner of calculation thereof. Promptly after the calculation of such Redemption Price, the Company shall give the Trustee notice thereof and the Trustee shall not be responsible for such calculation.

This Security is not repayable at the option of the Holder hereof and is not subject to the operation of any sinking fund.
If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.
The provisions of Section 1402 and Section 1403 of the Indenture relating to defeasance and covenant defeasance, respectively, shall apply to this Security. Pursuant to Section 1404(5) and Section 1404(6) of the Indenture, any such defeasance or covenant defeasance shall be conditioned on receipt of an Opinion of Counsel relating to the federal income tax consequences of such defeasance or covenant defeasance.
The Company will not pay any Additional Amounts to Holders that are not U.S. persons (including any modification to the definition of such term) in respect of any tax, assessment or governmental charge.
The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of all Securities at the time Outstanding to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Outstanding Securities, to waive compliance by the Company with certain provisions of the Indenture, and contains provisions permitting the Holders of specified percentages in principal amount, in certain instances of the Outstanding Securities of individual series and in other instances of all Securities at the time Outstanding, to waive on behalf of all of the Holders of Securities of such individual series or of the Holders of all Securities at the time Outstanding, as the case may be, certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.
As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount, in certain instances of the Securities of this series at the time Outstanding and in other instances of all Outstanding Securities, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of not less than a majority in principal amount of Securities of this series at the time Outstanding or of all Outstanding Securities, as the case may be, a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof (and premium, if any) or interest hereon on or after the respective due dates expressed herein.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or make provision as provided in Article Fourteen of the Indenture for the payment of the amount of principal of (and premium, if any) and interest on this Security herein provided, and at the times, place and rate, and in the coin or currency, herein prescribed.
As provided in the Indenture and subject to certain limitations therein and herein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.
The Securities of this series are issuable only in registered form without coupons in minimum denominations of $2,000 and any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series of a different authorized denomination, as requested by the Holder surrendering the same.
No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.
Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

(formerly The Bank of New York Trust Company, N.A.), as Trustee (successor to The Bank of New York) (herein called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the series of which this Security is a part), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered.

“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent (defined below) that has a maturity comparable to the remaining maturity of this Security (assuming, for this purpose, that this Security matured on October 15, 2046) and that would be used in accordance with customary financial practice to price new issues of corporate debt securities with a maturity comparable to the remaining term of the Securities. The investment banks from which the Company will select a Quotation Agent are BofA Securities, Inc., Citigroup Global Markets Inc. and Morgan Stanley & Co. LLC, or their

respective successors, or up to two other nationally recognized investment banking firms that are primary U.S. government securities dealers in New York City (each, a “Reference Treasury Dealer”). The Company will select one of the Reference Treasury Dealers to serve as its quotation agent (the “Quotation Agent”). If any of the firms referenced in the second preceding sentence ceases to be a primary dealer of U.S. government securities in New York City, the Company shall appoint another nationally recognized investment banking firm that is a primary dealer as a substitute.
“Comparable Treasury Price” means, for any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations given to the Trustee by the Reference Treasury Dealers for that Redemption Date after excluding the highest and lowest of those Reference Treasury Dealer Quotations (or only one of the highest or lowest of the Reference Treasury Dealer Quotations if there are more than one), or (2) if the Trustee is given fewer than four Reference Treasury Dealer Quotations, the average of all those quotations.
“Reference Treasury Dealer Quotation” means, with respect to any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the Trustee by a Reference Treasury Dealer as of 3:30 p.m., New York time, on the second Business Day preceding the date of the Redemption Notice. The Trustee shall seek Reference Treasury Dealer Quotations in respect of any Redemption Date from each of the then-existing Reference Treasury Dealers.
“Remaining Scheduled Payments” means, with respect to the principal amount of each Security being redeemed, the remaining scheduled payments of principal and interest on that Security that would be due after the related Redemption Date but for the redemption, assuming for such purpose that this Security matured on October 15, 2046. If, however, the Redemption Date is not an Interest Payment Date with respect to that Security, the amount of the next succeeding scheduled interest payment on that Security that would have been due will be deemed reduced by the amount of interest accrued on the Security to the Redemption Date.
On and after any Redemption Date, interest shall cease to accrue with respect to the Securities, or any portion of the Securities, called for redemption and for which the Redemption Price has been paid or made available for payment. On or prior to any Redemption Date, the Company shall deposit with the Paying Agent or the Trustee money sufficient to pay the Redemption Price on the Securities to be redeemed on such Redemption Date. If less than all of the Securities of this series are redeemed, the Trustee shall choose the Securities of this series to be redeemed by any method that it deems fair and appropriate, provided that if the Securities of this series are represented by one or more global Securities, interests in the Securities of this series will be selected for redemption by DTC in accordance with its standard procedures therefor.
Notwithstanding Section 1104 of the Indenture, the notice of any redemption referred to herein need not set forth the Redemption Price therefor but only the manner of calculation thereof. Promptly after the calculation of such Redemption Price, the Company shall give the Trustee notice thereof and the Trustee shall not be responsible for such calculation.

This Security is not repayable at the option of the Holder hereof and is not subject to the operation of any sinking fund.
If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.
The provisions of Section 1402 and Section 1403 of the Indenture relating to defeasance and covenant defeasance, respectively, shall apply to this Security. Pursuant to Section 1404(5) and Section 1404(6) of the Indenture, any such defeasance or covenant defeasance shall be conditioned on receipt of an Opinion of Counsel relating to the federal income tax consequences of such defeasance or covenant defeasance.
The Company will not pay any Additional Amounts to Holders that are not U.S. persons (including any modification to the definition of such term) in respect of any tax, assessment or governmental charge.
The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of all Securities at the time Outstanding to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Outstanding Securities, to waive compliance by the Company with certain provisions of the Indenture, and contains provisions permitting the Holders of specified percentages in principal amount, in certain instances of the Outstanding Securities of individual series and in other instances of all Securities at the time Outstanding, to waive on behalf of all of the Holders of Securities of such individual series or of the Holders of all Securities at the time Outstanding, as the case may be, certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.
As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount, in certain instances of the Securities of this series at the time Outstanding and in other instances of all Outstanding Securities, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have received from the Holders of not less than a majority in principal amount of Securities of this series at the time Outstanding or of all Outstanding Securities, as the case may be, a direction inconsistent with such request, and shall have failed to

institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof (and premium, if any) or interest hereon on or after the respective due dates expressed herein.
No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or make provision as provided in Article Fourteen of the Indenture for the payment of the amount of principal of (and premium, if any) and interest on this Security herein provided, and at the times, place and rate, and in the coin or currency, herein prescribed.

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Amended and Restated Indenture, dated as of May 1, 2001, as it may be supplemented from time to time (herein called the “Indenture”), between the Company (formerly known as United Technologies Corporation) and The Bank of New York Mellon Trust Company, N.A. (formerly The Bank of New York Trust Company, N.A.), as Trustee (successor to The Bank of New York) (herein called the “Trustee”, which term includes any successor trustee under the Indenture with respect to the series of which this Security is a part), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof. The Indenture does not limit the aggregate principal amount of the Securities or the Securities of this series that may be issued thereunder. Additional Securities of this series may be issued from time to time hereafter; provided that any such additional Securities that are not fungible with this Security for U.S. federal income tax purposes will have a separate CUSIP, ISIN and other identifying number than this Security.
The Company may, at its option, redeem all or any part of this Security. If it chooses to do so, it shall mail or electronically deliver according to the procedures of DTC a notice of redemption (the “Redemption Notice”) to the Holder hereof (with a copy to the Trustee) not less than 15 days and not more than 60 days before the Redemption Date. If this Security is redeemed prior to October 15, 2046, the Redemption Price shall equal the greater of (i) 100% of the principal amount of this Security to be redeemed or (ii) the sum of the present values of the Remaining Scheduled Payments on the principal amount of this Security to be redeemed, assuming for such purpose that this Security matured on October 15, 2046, discounted to the Redemption Date on a semiannual basis, assuming a 360-day year consisting of twelve 30-day months, at the Treasury Rate plus 25 basis points. If this Security is redeemed on or after October 15, 2046, the Redemption Price shall be 100% of the principal amount of this Security to be redeemed. In each case, the Redemption Price shall also include interest accrued to, but excluding, the Redemption Date on the principal balance of this Security to be redeemed.
“Treasury Rate” means, for any Redemption Date, the annual rate equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue equal to the Comparable Treasury Price, expressed as a percentage of its principal amount, for that Redemption Date.

The investment banks from which the Company will select a Quotation Agent are BofA Securities, Inc., Citigroup Global Markets Inc. and Morgan Stanley & Co. LLC, or their

respective successors, or up to two other nationally recognized investment banking firms that are primary U.S. government securities dealers in New York City (each, a “Reference Treasury Dealer”). The Company will select one of the Reference Treasury Dealers to serve as its quotation agent (the “Quotation Agent”).

“Comparable Treasury Price” means, for any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations given to the Trustee by the Reference Treasury Dealers for that Redemption Date after excluding the highest and lowest of those Reference Treasury Dealer Quotations (or only one of the highest or lowest of the Reference Treasury Dealer Quotations if there are more than one), or (2) if the Trustee is given fewer than four Reference Treasury Dealer Quotations, the average of all those quotations.
“Reference Treasury Dealer Quotation” means, with respect to any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the Trustee by a Reference Treasury Dealer as of 3:30 p.m., New York time, on the second Business Day preceding the date of the Redemption Notice. The Trustee shall seek Reference Treasury Dealer Quotations in respect of any Redemption Date from each of the then-existing Reference Treasury Dealers.
“Remaining Scheduled Payments” means, with respect to the principal amount of each Security being redeemed, the remaining scheduled payments of principal and interest on that Security that would be due after the related Redemption Date but for the redemption, assuming for such purpose that this Security matured on October 15, 2046. If, however, the Redemption Date is not an Interest Payment Date with respect to that Security, the amount of the next succeeding scheduled interest payment on that Security that would have been due will be deemed reduced by the amount of interest accrued on the Security to the Redemption Date.
On and after any Redemption Date, interest shall cease to accrue with respect to the Securities, or any portion of the Securities, called for redemption and for which the Redemption Price has been paid or made available for payment. On or prior to any Redemption Date, the Company shall deposit with the Paying Agent or the Trustee money sufficient to pay the Redemption Price on the Securities to be redeemed on such Redemption Date. If less than all of the Securities of this series are redeemed, the Trustee shall choose the Securities of this series to be redeemed by any method that it deems fair and appropriate, provided that if the Securities of this series are represented by one or more global Securities, interests in the Securities of this series will be selected for redemption by DTC in accordance with its standard procedures therefor.
Notwithstanding Section 1104 of the Indenture, the notice of any redemption referred to herein need not set forth the Redemption Price therefor but only the manner of calculation thereof. Promptly after the calculation of such Redemption Price, the Company shall give the Trustee notice thereof and the Trustee shall not be responsible for such calculation.

Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.
